We'll learn what polyatomic ions are. Polyatomic ions are created when a number of atoms come to together to form a group, and then that group has either a positive or a negative charge, which means that it can be either a cation or an anion. We discuss how protons and electrons balance to give a net charge, and then discuss some common polyatomic ions.

I wish all teachers taught like this.
i know right
our teacher showed this to us. close enough?? lol
Karnvir Heer same
Teachers in school are obviously just for examining us and not to teaching us - and saying who is of students more or less intelligent 🤢🤮
@@lol-mv1nb ok thanks again
this man makes me feel safe, makes me understand and like chemistry when I feel completely lost on a topic
This channel is why I'm not failing science. THANK YOU
*chemistry
@@enderman1058 lol yeah
@@enderman1058 he might have been a grade school student who took science
Real truth. Thank you sir
You are a life saver.
Bahahah u got a music account and ur kinda popular now
Absolutely
IKR
I really enjoyed your use of pre-written notes and the layout of the video which shows you speaking also makes the video more engaging. Great work
In the first 35 seconds of your video, you taught me more than my textbook has taught in 3 lessons! Thank you!
true
You completely saved me from dropping out of my class. I was starting to believe I had a learning disability until I came across your videos. Your teaching method is phenomenal and very comprehensible. Thank a lot
the nostalgia of watching this man many years after your last time using his video for a chemistry exam
can not express my gratitude
DUDE. Thank you so much for this. I'm taking a college chemistry course (for the first time in 25 years) that used a mishmash of other RUclips videos that confused more than it helped. Your video solved the dilemma. Thanks so much!
Tyler, I've been watching your videos since classes started. You're the only person that can help me understand and can rely on. Thanks so much
Tyler makes me wanna major in chemistry!! He got me through 4 YEARS of chemistry in high school and he's now getting me through college. I absolutely love him! so grateful for you mane!
Tyler,
Im up to 1:24 in your video. I understand how you have added up the protons ( H=1x4 + N=7 = 11) however i thought that the number of protons mimics electrons so why is there only 10 electrons and not 11?
Thanks Lee
The reason is because it is an ion, it has a charge, so protons and electrons don't equal each other. I made this video to address your question: ruclips.net/video/GyJBstOn4t4/видео.html
Tyler DeWitt Tyler, Thanks so much for replying to me you definitely solved my question . Just wondering how you made the video's you make i have to do one for an A&P assessment and would like to do something similar to yours? Thanks again Lee
+Tyler DeWitt How do you know whether an electron is lost or gained though?
+mmoore if there is like 5 to gain but 3 to loose obviously it will be easier to lose 3 than gain 5 😀but if you have like something that you have to gain 2 but loose 6 then it will be easier to lose 2
IFKR I DONT UNDERSTAND
Our science teacher calls him the hand gesture guy
+PerfectEnemy Same here...
Hehe 😄
Lmao
Hi - you mentioned you had a video on learning the polyatomic ions ? I can't seem to find it anywhere. Great videos by the way. Thanks for taking the time to do this.
I've just seen three of your videos and I can tell you that I've learned more in these 30 min than I have in two months in my COLLEGE COURSE FOR CHEM! THANK YOU SO MUCH KEEP DOING WHAT YOU DO!
So grateful for you! I've started watching your videos on topics before I go to my uni lectures, and just use the lectures to consolidate what I've learnt from you. Fantastic, thank you
wow, you're waaaay much more easier to understand than my science teacher, can you please be his replacement.
You're amazing!!! Every video is just spot on. I constantly have to do a small reminder of something in chem and it's so refreshing to just get a quick explanation and refresher!!!
Your knowledge is helping me through A level chemistry, thank you sir🙏
really loving the way you explain things clearly! thank you for priceless assistance helping people with studies
Can u also show how calculated the electrons of each polyatomic ions? I'm struggling with it
TYLER you are SAVING me-------- 2nd week of Chem (with no prior knowledge on the subject) A BIG THANK YOU
probably the bestest chemistry teacher on the planet 😊 your videos always work man...... its more easy to understand than any text book or else stuff.
8 years old and this is still better than any info i can get from my classes. Thank you
i love you so much.
Thanks Tyler, you have been so helpful. I am not very good in chemistry, but I need to pass a test...you are helping my a lot. God bless you!!!
I ve been trying to understand ions for a while now but he's such a good teacher that I easily caught on immediately !!
no. the protons and electrons are often different, which is what gives atoms a charge. watch my video called "What's an Ion?" for more information about this.
i know what an ion is, but you did not specify we started with any. You just combined 4 oxygen with a nitrogen so I assumed it was neutral atoms not ions. How was i to know you were using ions or why the electrons is different than protons
Jesus! thank you you have explained this better than any one else on this platofrm , you've earned yourself a subscriber
I'm a student in 2019. I'm taking AP chem, but never took any science class before (weird schedule conflict with my school.)
I think this channel will prevent me from failing this class. Thank you.
I love your videos! They're very helpful and easy to understand. I wish my professor taught more like you :)
Hey everyone, I'm here to help. If you have any questions or just want to learn more, click on the link in the description above. It'll take you to a page where you can ask me questions.
Good morning,
May I ask how did u count 32 electrons for the carbonate, as one atom of carbon contain 6 electrons, and 3 atoms of oxygen contain 24 electrons , the total is 30 not 32
Please how did you count the total number of electrons and the protons
@@germinbarakat5517 Im having the same problem. The ammonium should also have 11 electrons if i'm not wrong. 4 hydrogens = 4 electrons and one nitrogen = 7. I really dont get this
@@Filipk600because it lose an electron
i had the same prblem and when i searched up about it i found that one of the hydrogens are a positive ion so it doesnt have any electrons@@Filipk600
Did you delete your "How to Learn Polyatomic Ions" video? If so, could you link me to another video that you think may help out? Thank you!
Your video so wonderful! It really helps me to understand. It's like walking step by step. Thank so much!
thank you so much, you are the best teacher I know of and you have that rare insight regarding what is hard to understand and the talent to put it in an understandable simple form so thank you again
I’m confused how do you get 10 electrons instead of 11?
Thank you so much for these videos. You are an amazing teacher and I really found these easy and cool to understand. Thank you Tyler
I spent 4 days 17 hours 49 minutes and 20 seconds trying to figure out the polyatomic ion’s charge on my own whiteout almost any knowledge about chemistry 👍🏻
You saved me from wasting more of my useless time 👍🏻
Thank you! I am struggling in chemistry and this helped me a lot!
no. the protons and electrons are often different, which is what gives ions a charge. watch my video called "What's an Ion?" for more information about this.
Well explained and visually presented. Thanks for the video, Tyler!
You are the best. Thank you so much for your help. I do not know anyone who explains chemistry as clearly as you.
Tyler Sir.
Simply and awesome explanation. My hand gestures also like you.... thank you...
Love from "INDIA"
u r the great. i have scored well in chemistry when i was in 10th grade. now i m in 12th and i still get lots and lots of benefit out of you. thanks for doing these jobs.
thank you so much man, still helping out folks after 10 years.
appreciate
Wow. An amazing job teaching this subject! Thank you so much!
Your lectures are masterteaching!!!
I am now enjoying learning chemistry because I understand better now, thanks.
I really love studying Chemistry like this hope i could have a teacher like this
I have a Question:
for NH4: N has 7 protons and H4 has 4 protons So we have 11 protons.
for electrons: N has 7 electrons and H4 has 4 electrons giving 11 electrons.
so the net charge is 0.
where did I go wrong? How do I count the electrons correctly?
So I guess your gonna be my new chem teacher sense coronacation is now the rest of the school year, and my own teacher is using as our lessons. So good on you man
I am so glad I found your channel, you have saved me much overthinking
Helping me pass Chemistry in 2018. THANK YOU!!
Your teaching methods are very helpful...thank you!
Thank you so much you help me understand polyatomic ions and writing formulas!!! thank you so much, i need this for my school work.
One of the most clear chemistry video's I've seen.
Great job explaining atoms and ions! :) Thanks for the help!
If Indian techers would starting teaching like you . Then everybody will score good in exam . Love from India
Your videos are honestly the most useful thing since sliced bread
Holy... this was so much easier to understand than what any of my teachers have said!!! Thank you!!
I am so thankful rignt now omg, I got help from 3 teachers and never understood, it's magical his way to teach is so great, he gave me faith ahaha
everyone needs a teacher like you....hope u were my teacher
Dude! you're amazing I have a test to take tomorrow and my teacher isn't the best teacher but I sure am prepared! Thanks!
the best teacher in the whole world.......
I truly wish if all my teachers are like him !!
yup
Helped so much. Thank you so muCH. I was havIng difficulty grasping this topic.
This video helped me so much! I wish my teacher explained it like this
You are really amazing!! Please please make a tutorial about reactions, so far Synthesis reaction is the only one I can fully understand. From my experience, when the discussion is from you, I can briefly understand it not like when my chem teacher is the one teaching it. He's so serious and everything. And he also is always absent so what happens is that he can't briefly go through a topic.
God Bless this guy! I was kinda lost from just reading the book. Thank you sir!
you're really good at explaining! i've been trying to find out what their properties are... do you know?
In 5 minutes this video answered 100 questions. Thank you.
dude I like ur gestures
Keep up the good work, you are better than my grade 10 science teacher I can tell you that!
Thank you for the vedic. I have one question. How do you know that electrons in NH4+ is ten? I assume that we don't know NH4 is 1+. Thank you for your time.
Thanks for all of your videos! They are so helpful. YOU ROCK!
You are a REAL teacher, thank you soo much
This guy is the best teacher on RUclips. I wish he would do soil science.
Best Explanation; im crying with appreciation
such are good and useful videos and I learn a lot of things and cleared to my many concepts about atom structure, electrons and protons ........................thanks,
Sir................Please keep up to date
You sir are a Chemistry God! Thank you very much for these videos.
Your Video helps me a lot. Thank you for making this awesome video.
You explain really well
Thank you so much! I was so confused now I can write my notes! Subbed!!!!!
You are a life saver!! I tried looking for the videos : How to learn polyatomic Ions and How are polyatomic Ions made but could not find them. are they named something else?
You are a good teacher for teaching us
loving your teaching style.
Your lectures really help ,thank for that
for anyone wondering how to count the protons and electrons, He explains this in "bonding poly atomic ions and compounds."
I think to find the number of electrons you have to add up the charges of each atom in the polyatomic ion and that will tell you how much more or less the electrons are compared to the protons. For example, for ammonium, there are 4 hydrogens each containing 1 proton. Four hydrogen= 4 protons. Then, nitrogen has 7 protons, and when u add it with with the hydrogens you get 11 protons. Now, to find the number of electrons for ammonium, you find the charge hydrogen and nitrogen in ammonium. Hydrogen each have 1+ charge, 4 hydrogens = 4+. Nitrogen has a charge of 3-. Add all of it and you get 1+. That means there is 1 more proton than electron. It's calculated that there are 11 protons. As a result, there will obviously be 10 electrons.
I was looking for the other two videos which u mentioned in the end but I couldn't find them
How to learn the polyatomic ions.
How are polyatomic ions made.
You are a great tutor. I feel like am in a physical class. Keep it up sir.
Will a sodium atom with 11 protons and 11 electrons loose its electrons into 'thin' air or there has to be an atom to receive receive the electrons?
Thank you sir
It was really a difficult topic I was having a lot of doubt
But sir you solve all my doubts 😃
Thanks buddy, this was very clear and helpful.
2:49 how do you know how many electrons does the substance have
I dont understand how you are counding the electrons...? please help.
@Tyler DeWitt
I cannot find your video "How to learn the Polyatomic Ions" or how to memorize them- has it been deleted? can you provide a link?
PS.. i will continue to comment that you are the real MVP because you are saving my college career. Thank you times a million.
You are a legend man! You have single handly rescued me from the depths of ignorance! I am going to use what you have taught to sound like a genius in my chem class😆
Hi Tylerr I know this is an old video but I wish you could answer my question why sulfite is 2- I think it should be 0 because sulfur can form sp^3d^2 which mean it van share 6 electrons and that what 3 O atoms need
Thank you so much i wish you were our teacher inn all subjects
I can't find the "learning Polyatomic ions" video you were talking about at 4:07
Can anyone find that?
+Joshua Walters I can't find it either. : (
Same, not there
2017 and same
however, he did a great job
So no one ever found it huh?
@@alanamarie8669 Nope.
Only video that helped me with this!!! Thank you!!
