I want to personally let Hank know, if these videos came out while I was in highschool, I think i would have become a molecular biologist... While i may have not gone down this career path, i know WITHOUT A DOUBT you inspire many kids to reach a level of academic competence they would have not attempted with out you. Hank, thank you for the amount of work you do. I notice you do virtually all of the writing for the show, and you explain things is such a relaxed normal no stress manor.. Thanks again!
Bacon Spaceman That's awesome Bacon Spaceman. I hope you don't let anybody get in your way either. I am 34 years old, but when I was young, I let my crazy dad get in my way of my attraction to chemistry. I wanted his approval, but instead I should distanced myself & found better role models. I am 34, now I'm starting to rekindle my old lost interests. Good Luck Brother =^) =^)
As a high school student currently struggling in chemistry, I can say that I am still thoroughly confused, but now I'm confused and entertained. I am unlikely to become a molecular biologist.
I just received one of the highest compliments! I referred a student to this video to review for a quiz--and she came back and told me that I am just like Hank Green! She said that as she watched it she thought he was just the male version of me! How fantastic is that?!? I can't stop smiling, haha

How to distinguish between cations and anions: -Cations start with CAT, cats = positivity and happiness. A functional household cannot be without a cat. -Anions start with An. You know what else starts with An? ANXIETY! ANOREXIA! An sentence like this makes me uncomfortable. So much negativity.
+sharmoota Woah... That's kinda complicated lol o.o ...Here's how I remember it: CATions are PAWSitive. Remember that, and you don't even have to remember anions.
cats have paws so they are pawsitive, so many things have paws... just why also, many functional households(approximately 33%) cannot function with a cat, while another large amount function without a cat
Thank you so much for this - I have a chemistry test coming up and I am preparing to fit these all in to my normal study routine. You explain things better than my textbook.
The prefix "Per" actually comes from the word "hyper", which is the opposite of "hypo". They remove the "hy" from "per" because many people confuse hyper with hypo. When using "per" and "hypo", it is more difficult to confuse one with the other.
I'm a grad student studying environmental science and this was the most straight forward video I've seen regarding the naming of potential pollutants that I have to deal with
I am a math and science tutor for an easily distracted student and when I can't be there and she gets stuck I send her links to these videos. They are so great because the topic I am looking for has always been covered. Plus the way Hank explains it is easy to follow and interesting it so she doesn't get bored and loose focus. Thank you so much!
This is definitely the most productive subscription I have ever made on RUclips. SUBSCRIBED! Finally someone who doesn't waste time with explaining things.
I Really Appreciate This Series Of Crash Course Chemistry As It Has Been An Amazing Support For Me During My A'levels, Even-Though They Are A Bit Fast, If You Are Listening To It Carefully You Can Really Understand It In A Very Simple Way. THANKS HANK GREEN FOR THESE AMAZINGLY CREATIVE VIDEOS.
I'm an engineering student who has passed chem and I still watch your videos just because they are so damn good. Great production quality, content and personality. Cheers.
Cause acids are sour, if you ATE it, you'ld say "IC" (like icky) and ITE goes with OUS because combined they're almost righteous. That's how I remember
I watch these multiple times before a test and they help a lot with tips for memorization and explanations. Your videos have helped me on soooooo many tests for years now
hank i know you guys aren't really in to math but could one of you PLEASE do a crash corse physics lesson? your chem playlist covers exactly what im learning right now and i understand this so much more than the way im taught at school. physics would help!
Just a tip for remembering polyatomic ions- Nick the Camel ate Clam Supper in Phoenix For every capitalized word, the first letter(s) is the non-oxygen atom The number of vowels in the capitalized words are the number of oxygen atoms in that ion the number of constantans is the charge ATE is the ending to all of the ions on the list Hope this helps!
Yes, of course we learn it in school! But if you haven't learned something in a long time, sometimes you forget, so this is helpful for people who learned these things a long time ago.
The best thing i like about Crash course it that it covers pretty deep about the topic and makes things that are hard and simple easy Thanks a lot crash course!!!!!!! And also the summary at the end of the video is very very very helpfull...💚💚💚💚
I usually refrain from saying "I learned more here than I did in class" because, realistically, these are afterall crash course series posted for ten minutes once a week instead of every day for 90 minutes. But in this case, this video did help me understand the use of some of the prefixes and suffixes for acids better than my AP Chem class did, so thank you for that :D
Crash Course Team: Have you thought about compiling a list of FAQs that follow the release of each episode so that in the event that a teacher wants to use your videos as a lecture replacement they could plan activities to address the FAQs? Perhaps a forum would be a better net to catch questions in, and perhaps have volunteers help answer questions. (I would definitely volunteer my time to answering ppl's Qs and helping to develop a FAQ for each episode. Btw, I'm a chemistry teacher.)
these videos are the only reason I'm going to pass my chemistry final. I didn't realize how hard college chemistry was until I decided I should take it. I'm so thankful for these videos.
The IUPAC names for acids are even crazier. Chlorous acid (HClO2) is hydridodioxidochlorine. Sulphuric acid (H2SO4) is dihydroxidodioxidosulphur. Basically hydrogens bonded to the central atom are hydrido, OH's are hydroxido and oxygens are oxido. As weird as this way of naming is it actually represents structure and the properties really well.
Honestly I just need to say thank you Hank, I have the worst teacher in the history of chemistry and I think now with the help with your videos I should be able to pass!
Hank, I would really like to thank you for making these videos, for without them I definitely would have failed my chemistry test this morning. Your #1 on my hug bucket list.
Thank you for this wonderful explanation of language and naming. Despite having a not insignificant amount of university chemistry, I never understood WHY different ions/acids were named what they were.
With regard to the Acid/Anion naming, I tried this out with Cl, S and P, and I was wondering if it also works with N; Pernitric Acid ~ HNO4 Pernitrite ~ NO4(-) Nitric Acid ~ HNO3 Nitrate ~ NO3(-) Nitrous Acid ~ HNO2 Nitrite ~ NO2(-) Hyponitric Acid ~ HNO Hyponitrite ~ NO(-) Hydronitric Acid ~ H3N Nitride ~ N(3-) Does this mean that Hydronitric Acid is the same as Nitrogen Trihydride (Ammonia)? Thank you!!
I am confused. my mother tongue is German, the German dialect of Chemistrian is a bit different than the English one. And as do understand a bit of French and Dutch, I prefer the rainy meadow in Belgium.
Hank: Master of the Universe, (of Chemistry and Biology.) This was the best piece of educational video that I've ever seen. The concepts are dull and hard, and the CC team have managed to make them fun and inviting; or to put it into Internetian: All of my feels for the winning here. G.O.
ah this is so helpful, I'm doing prelim chemistry (year 11 in australia) and I'm doing it through distance education so I don't attend a mainstream school, this has helped me understand my first unit of work so much!
I have learned something about myself and that is I am weird. Even though this video exist and it hurts my brain, and even though I do not like math. I love the idea of going to college and majoring in mechanical engineer, and minoring in chemistry. I must like torture, both of these seem hard as balls, but there is something magical about them that draws me to them. My brain may explode by the end of college when I go back but it will be worth a try.
Roy Fresh It isn't that I hate math (I always word things wrong) for some reason I have a mental block on it. I love the idea of learning the math I do I mean it gives you the ability to predict a lot of stuff. It will be extra hard for me, but I figured out how to work around it. I need to see the math worked out in real life like what can you use it for, I don't know how come but when I watched a video of how you would use some formula I forgot now sadly but it clicked my brain said yeah I got this, but if you throw a book at me and expect me to learn it on my own my brain doesn't want to do it that way. When I was in college the first time they threw a book at us basically and said you have to do it out of the book and do it online. They basically threw you into the deep end of the pool and expected you to swim, and the only way I could learn it was via youtube videos, the book never works for me. I honestly think I have it, it will be difficult but I think I do, once I go back to college and get beyond speech class I will make math my bitch. What do you think of masters in mechanical engineer and minoring in chemistry?
Roy Fresh I know it will be balls hard but I drool at the prospect of learning it (literally). The only obstacle I really truly face is the speech class. I have been out of college myself I will be about 28 or so when I go back if life events doesn't stop me from going back. What I really hate is that I live in the capital of my state in a big city and the colleges around here do not have what I need, and these are some major colleges. I have to travel over an hour to get to a college that will do. I am glad I completed some college work before having to quit. Hell when I was originally going to college I wasn't sure what I wanted to do I just went for the fun of it to see if I was smart at all. I quit with a 3.7 gpa so I guess I was kinda smart. Right now events in my life are not so great to say the least so going to college may not happen which pisses me off because I really really want to go. I think I might even be ready for speech class, I mean I used to not comment much and now I feel like bruce lee with the comment wars that surround me and well if I can improve to the point of being able to comment on stuff and have people attack me all at once and be able to win per se I think I can do speech. I got into an argument with someone and I dragged him through the mud, and he had a masters in science education talked with a friend and he was an 11th grade biology teacher I am not going to lie that gave my ego a boost. 8th grade drop out over here, G.E.D diploma and at most a year of college and I did that, I always wanted to hand a teachers ass to him on a silver platter but never thought I would have the chance, much less one so high on the food chain, but I found out through my ex wife that being a teacher does not mean you are smart she was as dumb as a bag of bricks, and he made my jaw drop in awe of his stupidity. Sorry the latter was unnecessary but I think that also helped me realize my potential, then there is a debate with bill nye and richard dawkins and so and so forth I call it the gather of the great minds that helped me, and then there is a lot of people calling me smart (including an outside source a professor of mine) all the time so I decided why not. My goal which is laughable is to somehow go to the moon or mars and maybe bring back a few moon rocks (or martian rocks of course after nasa examines them), my mom said I better bring her some back if I go to the moon lol. I have my life planned out for after college I have issues with planning stuff out. I was wanting to work with nasa for a while pay stuff off and go to the moon, and eventually go into what I call leisure work life where I become a freelance mechanical engineer that way I work around my schedule, even have a website concept down. Oy vey I really need to stop with these rants, I never used to like writing much less now but I never seem to make anything short when it comes to writing.
Roy Marth I just dove into a robotics class online that is free man did I jump into the pool with the sharks and alligators. I am doing physics which they expect me to know calculus for which lead me to learn a lot of calculus in 3 days which still may not suffice I haven't even finished algebra courses. I did decent though I made a 60 on my first test and besides this is not a certificate class so I earn nothing but knowledge which is good enough for me albeit there is no place around where I live to continue robotics so this is all I will ever learn from a school about robotics. I have to say my brain hurts from it but I am slowly getting it. I had to learn trig which was not hard well the part I learned the soh cah toa and it was fun. Also mechanical engineering turns out not to be what I wanted sorry never went through with it, but am going to do technical school soon and do a bunch of different course to get the skills I wanted. Mechanical engineering after a lot of studying up on it you do nothing that I want to do with it in fact you do not even use the math that you learn half the time it disappointed me but at least I found out. You are most of the time a glorified paper pusher who is also a scapegoat well in a lot of cases and you barely use pre algebra even though you learn some really really difficult stuff.
+BillTheBox well in most schools in Flanders it's Dutch, French and English with an option to do German or Spanish. The official languages are Dutch, French and German ;-)
The numbers people use today were invented by Arabs :) same as most aspects of algebra and physics. They also discovered most aspects of medicine and they were one of the first people to introduce the number 0 before that people just called it nothing, they also dissected the eye and made a camera model very close to the one you use today on your smartphone so yeah do your research about the Islamic golden age and don't get too lost when you hear the word Arab. HAVE A NICE DAY :)
Thank you very much Hank your crash course chemistry videos have been so much help to me this year in my chem class and they help me to study for my tests. Again thank you evey one from crash course chemistry :).
im 17, starting my sophomore year of college, and I've never taken a chemistry class...until now. and yes, i am very PERplexed, especially with the process of naming the elements and etc. this table was VERY helpful, so i am very grateful to Hank. but just to solidify the information, i was wondering if anyone had the links to any other helpful videos or sites? any help would be appreciated!
+Annsley Elizabeth Lowe I used Khan Academy last year for Bio, but I don't know how good their Chem videos are. I like Khan Academy cuz they explain things a little differently or in more depth; you should check them out! www.khanacademy.org/science/chemistry
According to Wikipedia (I got curious and looked it up), Cation/Cathode and Anion/Anode have the same Greek root words. An anion (−), from the Greek word ἄνω (ánō), meaning "up", is an ion with more electrons than protons, giving it a net negative charge. A cation (+), from the Greek word κατά (katá), meaning "down", is an ion with fewer electrons than protons, giving it a positive charge. And that's why your Anode has a negative charge and your Cathode has a positive charge.

Thanks again!
I know, i am 13, and now i want to do this for a living, but i still have 5-6 years to weigh my options for college.
Bacon Spaceman
That's awesome Bacon Spaceman. I hope you don't let anybody get in your way either.
I am 34 years old, but when I was young, I let my crazy dad get in my way of my attraction to chemistry. I wanted his approval, but instead I should distanced myself & found better role models. I am 34, now I'm starting to rekindle my old lost interests. Good Luck Brother =^) =^)
Abyssal Nocturnus you speak for all of us here brother.
Abyssal Nocturnus i have watched crash course and scishow since i was 7
As a high school student currently struggling in chemistry, I can say that I am still thoroughly confused, but now I'm confused and entertained. I am unlikely to become a molecular biologist.
I just HATE it when I randomly wake up in Belgium. It's such a hassle!
RedheadDane Il n’y a pas une problème pour moi
Thomas Burnett oui
What did u just say
Titan Boi je dit oui, est-ce que tu parlez en français?
Ryan P
non sis
I just received one of the highest compliments! I referred a student to this video to review for a quiz--and she came back and told me that I am just like Hank Green! She said that as she watched it she thought he was just the male version of me! How fantastic is that?!? I can't stop smiling, haha
caroljoyath2o thats wild
i made up a way to remember the -ATE, -IC,-ITE,-OUS!
I ATE and now im sICk
that bITE was poisonOUS
+Irene Wang yes
respect girl u are awesome!
Thats very unique and interesting
Thats why asians are smart
I really like that thanks heaps
Im in college chemistry and I think these videos are going to be the only way I pass my class. Thanks, crash course. You're awesome as usual
In case anyone was wondering, they were saying "What are you doing in the rain?"
Margaret Ashton when
omg they said when😭💀💀
it was actually what. i have french as a subject at school. and qu'est-ce que is most deffiniatly what.
As a Belgian person, that intro was hilarious
As a Dutch person, too, although those last two 'languages' were clearly just different accents
@@petra5979 ja maar dialecten zijn toch ook verschillende talen ofzo, want vlaams was vgm ook zo'n aparte taal en dat was die 2e.
Fak Vlaams Belang
That was the most confusing and hilarious openings i've ever seen

How to distinguish between cations and anions:
-Cations start with CAT, cats = positivity and happiness. A functional household cannot be without a cat.
-Anions start with An. You know what else starts with An? ANXIETY! ANOREXIA! An sentence like this makes me uncomfortable. So much negativity.
Huntsta123 Haha glad to be of help
+sharmoota Woah... That's kinda complicated lol o.o ...Here's how I remember it: CATions are PAWSitive. Remember that, and you don't even have to remember anions.
War Machine Thanks lmao
cats have paws so they are pawsitive, so many things have paws... just why
also, many functional households(approximately 33%) cannot function with a cat, while another large amount function without a cat
Mingyang Wang no ur wrong
As a Belgian, I appreciate this episode slightly more than all the others
I'm belgian and I approve this message
i want some belgian chocolate
milka :D oh thats switz
Vasco Neto i miss Europę
I'm Belgian too and I, too, approve this message.
I watched this video(s) before taking Chemistry in school. Now i understand everything there, and speak Chemistrian. Go Crash Course!
Thank you so much for this - I have a chemistry test coming up and I am preparing to fit these all in to my normal study routine. You explain things better than my textbook.
Did you hear about the dead chemistry student?
Apparently his mother gave him a Pb and jelly sandwich for lunch.......
Kevin Hsieh lol!!!thanx coz you just lifted up my mood!
NO! We need to take all of these terrible chemistry jokes...
And Barium!
Did they at least Barium?
Kevin Hsieh i hate u. Lol
Only make those jokes *periodically* please
The prefix "Per" actually comes from the word "hyper", which is the opposite of "hypo". They remove the "hy" from "per" because many people confuse hyper with hypo. When using "per" and "hypo", it is more difficult to confuse one with the other.
exactly. its greek not latin.
I'm a grad student studying environmental science and this was the most straight forward video I've seen regarding the naming of potential pollutants that I have to deal with
This sounds hilarious if you watch it at 0.5 speed, sounds like a drunk chemist
Thank you so much, I needed this in my life.
Kristen Karcz how？？？
Sharon Liu if you watch on pc then you can go on the settings bar and change the speed
Yan-kang Qi thx😄
omg thank you it's beautiful

i should have just watched all of these for 4 months instead of taking intro to chm.
Some colleges don't give you a choice if you haven't taken chem in the last year
This is definitely the most productive subscription I have ever made on RUclips.
SUBSCRIBED! Finally someone who doesn't waste time with explaining things.
The guy in the cartoon with the mustache looks like ron swanson

I Really Appreciate This Series Of Crash Course Chemistry As It Has Been An Amazing Support For Me During My A'levels, Even-Though They Are A Bit Fast, If You Are Listening To It Carefully You Can Really Understand It In A Very Simple Way.
THANKS HANK GREEN FOR THESE AMAZINGLY CREATIVE VIDEOS.
As someone who studies the more language based side of things, this was always my favourite part of chemistry.
I'm an engineering student who has passed chem and I still watch your videos just because they are so damn good. Great production quality, content and personality. Cheers.
My college needs to fire my chemistry professor and put these videos up instead.
If my Chemistry teacher had show this to us at the beginning of the year, life would have made more sense. I am jelly of you.
I remember Cations are positive because the t looks like a + sign. Ca+ion
Congratulations of having the best Chemistry consultant in the world!
I have a quiz tomorrow and I think I'm just going to accept failure for this one
Did you fail
+Alex Stammel we'll never know
Kush Ghatlia lol I don't think I did
yep, and because I failed at chemistry almost completely, I'm thinking about how life will be living as a hobo when I'm 40
Quizzes suck mate but I have my own lab in my garage and I know more about chemical compounds and the periodic table more than my teachers ahaha
Cause acids are sour, if you ATE it, you'ld say "IC" (like icky)
and ITE goes with OUS because combined they're almost righteous.
That's how I remember
Thank you for this channel. I would never be able to pass chemistry without your charming and memorable teaching style. You're the best hank!
I watch these multiple times before a test and they help a lot with tips for memorization and explanations. Your videos have helped me on soooooo many tests for years now
hank i know you guys aren't really in to math but could one of you PLEASE do a crash corse physics lesson? your chem playlist covers exactly what im learning right now and i understand this so much more than the way im taught at school. physics would help!
Hank, thank you for helping me pull from the depths of my brain the things I learned in high school and have since forgotten.
I have two tests tomorrow and Crash Course is my only hope of passisng
Just a tip for remembering polyatomic ions-
Nick the Camel ate Clam Supper in Phoenix
For every capitalized word, the first letter(s) is the non-oxygen atom
The number of vowels in the capitalized words are the number of oxygen atoms in that ion
the number of constantans is the charge
ATE is the ending to all of the ions on the list
Hope this helps!
Yes, of course we learn it in school! But if you haven't learned something in a long time, sometimes you forget, so this is helpful for people who learned these things a long time ago.
LOVED THAT INTRO!
The best thing i like about Crash course it that it covers pretty deep about the topic and makes things that are hard and simple easy
Thanks a lot crash course!!!!!!!
And also the summary at the end of the video is very very very helpfull...💚💚💚💚
I usually refrain from saying "I learned more here than I did in class" because, realistically, these are afterall crash course series posted for ten minutes once a week instead of every day for 90 minutes. But in this case, this video did help me understand the use of some of the prefixes and suffixes for acids better than my AP Chem class did, so thank you for that :D
Crash Course Team: Have you thought about compiling a list of FAQs that follow the release of each episode so that in the event that a teacher wants to use your videos as a lecture replacement they could plan activities to address the FAQs?

these videos are the only reason I'm going to pass my chemistry final. I didn't realize how hard college chemistry was until I decided I should take it. I'm so thankful for these videos.
yeah you see this is the type of stuff they should teach us at school. but since it isn't taught to us at school, thank you guys!

As weird as this way of naming is it actually represents structure and the properties really well.
"nice"
I have been confused on acids for forever and my teacher could not explain it to me. You literally just did in five seconds thank you
Honestly I just need to say thank you Hank, I have the worst teacher in the history of chemistry and I think now with the help with your videos I should be able to pass!
I love crash course. My teacher plays these and they help us A LOT!
Thanking God you exist. I can finally understand chemistry
Thank you so much! This just clarified EVERYTHING my professor just breezed through in lecture...
You are such a better teacher than my science teacher.
Hank, I would really like to thank you for making these videos, for without them I definitely would have failed my chemistry test this morning. Your #1 on my hug bucket list.
I now started loving physical chemistry 😊🔥🔥pro teacher🔥🔥
Thank you for this wonderful explanation of language and naming. Despite having a not insignificant amount of university chemistry, I never understood WHY different ions/acids were named what they were.
I'm pretty sure Hank just explained a topic in 10 minutes clearer than my teacher did in 5 days...
If only we had teachers like this
With regard to the Acid/Anion naming, I tried this out with Cl, S and P, and I was wondering if it also works with N;
Pernitric Acid ~ HNO4 Pernitrite ~ NO4(-)
Nitric Acid ~ HNO3 Nitrate ~ NO3(-)
Nitrous Acid ~ HNO2 Nitrite ~ NO2(-)
Hyponitric Acid ~ HNO Hyponitrite ~ NO(-)
Hydronitric Acid ~ H3N Nitride ~ N(3-)
Does this mean that Hydronitric Acid is the same as Nitrogen Trihydride (Ammonia)?
Thank you!!
I am confused. my mother tongue is German, the German dialect of Chemistrian is a bit different than the English one. And as do understand a bit of French and Dutch, I prefer the rainy meadow in Belgium.
perfect - to complete something thoroughly.
that's pretty deep if you think about it
4:38
I heard Hank breathe...... Never thought I'd see this day😱😂😂😂
Hank: Master of the Universe, (of Chemistry and Biology.) This was the best piece of educational video that I've ever seen. The concepts are dull and hard, and the CC team have managed to make them fun and inviting; or to put it into Internetian: All of my feels for the winning here. G.O.
We're still the same, we just have a new name! :)
I find it awesome that people are actually looking for what essentially amounts to homework. Pretty freaking sweet.
I'm dutch and I got so confused when there was dutch in this episode... It's really weird to hear your native language when you don't expect it XD
I appreciate your video so much. Without them learning this would be almost unbearable. You're doing an amazing job!
I haven't gotten to these topics yet in class, but thanks for the pre-knowledge! You guys are awesome!
Bow ties are cool ( i like your picture :p )
Thank you so much, Hank! This is helping me survive college chemistry!
Yall realize in 10 years we'll look back at John Green in the same legendary status of Bill Nye
ah this is so helpful, I'm doing prelim chemistry (year 11 in australia) and I'm doing it through distance education so I don't attend a mainstream school, this has helped me understand my first unit of work so much!
Well. I'm failing that class.
LOL
Trash Co Got midterms coming up!
well did you fail
Same question .. did u fail ?
This might be my favorite crashcourse episode ever! ..... so far.....
I think my brain just exploded this is an amazing video
OMG thank you Hank for that table. Literally saved my exam result!!! (:
I have learned something about myself and that is I am weird. Even though this video exist and it hurts my brain, and even though I do not like math.

Right now events in my life are not so great to say the least so going to college may not happen which pisses me off because I really really want to go. I think I might even be ready for speech class, I mean I used to not comment much and now I feel like bruce lee with the comment wars that surround me and well if I can improve to the point of being able to comment on stuff and have people attack me all at once and be able to win per se I think I can do speech. I got into an argument with someone and I dragged him through the mud, and he had a masters in science education talked with a friend and he was an 11th grade biology teacher I am not going to lie that gave my ego a boost. 8th grade drop out over here, G.E.D diploma and at most a year of college and I did that, I always wanted to hand a teachers ass to him on a silver platter but never thought I would have the chance, much less one so high on the food chain, but I found out through my ex wife that being a teacher does not mean you are smart she was as dumb as a bag of bricks, and he made my jaw drop in awe of his stupidity. Sorry the latter was unnecessary but I think that also helped me realize my potential, then there is a debate with bill nye and richard dawkins and so and so forth I call it the gather of the great minds that helped me, and then there is a lot of people calling me smart (including an outside source a professor of mine) all the time so I decided why not. My goal which is laughable is to somehow go to the moon or mars and maybe bring back a few moon rocks (or martian rocks of course after nasa examines them), my mom said I better bring her some back if I go to the moon lol. I have my life planned out for after college I have issues with planning stuff out. I was wanting to work with nasa for a while pay stuff off and go to the moon, and eventually go into what I call leisure work life where I become a freelance mechanical engineer that way I work around my schedule, even have a website concept down. Oy vey I really need to stop with these rants, I never used to like writing much less now but I never seem to make anything short when it comes to writing.
I am like that too man.
Grim reaper I have trouble with math too but I also want to learn Engineering.
Roy Marth I just dove into a robotics class online that is free man did I jump into the pool with the sharks and alligators. I am doing physics which they expect me to know calculus for which lead me to learn a lot of calculus in 3 days which still may not suffice I haven't even finished algebra courses. I did decent though I made a 60 on my first test and besides this is not a certificate class so I earn nothing but knowledge which is good enough for me albeit there is no place around where I live to continue robotics so this is all I will ever learn from a school about robotics. I have to say my brain hurts from it but I am slowly getting it. I had to learn trig which was not hard well the part I learned the soh cah toa and it was fun. Also mechanical engineering turns out not to be what I wanted sorry never went through with it, but am going to do technical school soon and do a bunch of different course to get the skills I wanted. Mechanical engineering after a lot of studying up on it you do nothing that I want to do with it in fact you do not even use the math that you learn half the time it disappointed me but at least I found out. You are most of the time a glorified paper pusher who is also a scapegoat well in a lot of cases and you barely use pre algebra even though you learn some really really difficult stuff.
This will help me seeing as I am entering into AP Chemistry this year. Thanks Hank!
Now I can make all of my friends think I'm smart! :D
Carrot Slice I
Really Real and your dumb
@@ReallyReal_1 you're*
yep! that is indeed very helpful!
It is another reason to love chemistry! it is very fluid and simplistic and useful!
You got it :)
You have no idea how much this helps with the AP Chemistry test on Monday （ ´∀｀）
Would it be cool to name my pet feline "Cation"?
I love you for that.
Killa Luigi XD
Bro! your cat is a transformer!
Hannah Goad Electrical or robot. Because I thought the Transformers were robots.
only if you use the proper rules of English. its pronounced "cation".
Mental breakdowns about college chem are not as bad when i can turn to you @CrashCourse . Thanks for that :D
Yay, I'm from Belgium although we don't speak several languages. There are three offical languages and a whole load of dialects per region ^_^
+FailGirlGamer idk where you live in belgium but I speak 3 languages, and that's the minimum I can take at school, some people take 4 lol
+BillTheBox well in most schools in Flanders it's Dutch, French and English with an option to do German or Spanish. The official languages are Dutch, French and German ;-)
What were those people saying at the intro?
+jillian patricia sy what are you doing outside in the rain ;)
I am from Belgium and speak Dutch, French, English and German
wow! these explanations make chemistry so much easier to understand! Those tips are just a bonus>
THANK YOU
Who's ready for tomorrow's AP Chem exam?
thanks for the table of contents! very very useful & easy to understand
I "ate" and I felt S"ic"k
Do not floss and get Gingiv"ite" "ous"
Watched this in Chemistry this morning! Life = Made.
listen,,, u had me till 5:20.. then u lost me
same
The numbers people use today were invented by Arabs :) same as most aspects of algebra and physics. They also discovered most aspects of medicine and they were one of the first people to introduce the number 0 before that people just called it nothing, they also dissected the eye and made a camera model very close to the one you use today on your smartphone so yeah do your research about the Islamic golden age and don't get too lost when you hear the word Arab.
HAVE A NICE DAY :)
Thank you very much Hank your crash course chemistry videos have been so much help to me this year in my chem class and they help me to study for my tests. Again thank you evey one from crash course chemistry :).
#HankForPresident
I nearly wept from joy when I saw that table at the end. Thank you so so so much.
im 17, starting my sophomore year of college, and I've never taken a chemistry class...until now. and yes, i am very PERplexed, especially with the process of naming the elements and etc. this table was VERY helpful, so i am very grateful to Hank. but just to solidify the information, i was wondering if anyone had the links to any other helpful videos or sites? any help would be appreciated!
+Annsley Elizabeth Lowe I used Khan Academy last year for Bio, but I don't know how good their Chem videos are. I like Khan Academy cuz they explain things a little differently or in more depth; you should check them out! www.khanacademy.org/science/chemistry
lfgiraffe thank you! i actually went and checked a few of the videos out and they're great! :)
thank you soooo much!! i'm sure that by the end of this semester i will have used all of these resources!!
***** thank you soooo much!! i'm sure that by the end of this semester i will have used all of these resources!!
***** i looked at some of his that actually got me through my last test! and I'm a Biology major actually
This makes SO much more sense than the first time I tried to cram these rules into my brain
Now i wanna visit Belgium... :|
wait, im in germany, i just can do it XD
Another excellent lesson. Thank you for the chart especially.
I agree (although I was not a chem major). This part came naturally to me, but naming organics...that is another story all together.
But magic land does!
According to Wikipedia (I got curious and looked it up),
Cation/Cathode and Anion/Anode have the same Greek root words.
An anion (−), from the Greek word ἄνω (ánō), meaning "up", is an ion with more electrons than protons, giving it a net negative charge. A cation (+), from the Greek word κατά (katá), meaning "down", is an ion with fewer electrons than protons, giving it a positive charge.
And that's why your Anode has a negative charge and your Cathode has a positive charge.
Trump impersonation @6:13
wow how did u catch that lol that was actually good :D
Freaking Crash Course! These videos should be viral.
I can't be the only one here who has their chemistry final exam tomorrow ._.
twins!
***** :O (btw I failed that final)
Yeah it's tomorrow. I'm playing Xbox and "yoloing" it
