"Well neon is completely satisfied, it doesn't wanna even deal with any of this reaction business and bonding business. It's like, 'Y'know what, I've achieved happiness in life.'" I have never related to an element more. I'd die for you neon.
" You know what? I've achieved happiness in life, don't mess with my electron!" - Ne LOL! Making that into a shirt would be amazing. XD As a home schooled high school student, thank you for making science so much easier to understand. :)
So freaking helpful. My teacher tried explaining it to me, but a lot if it went over my head. Watched this video one time, and it all makes so much sense!
WOW! I loved your teaching! I just texted two of your videos on trends to all of my chemistry study pals. We are so grateful! Thanks a gazillion! You fill my outer shell with happiness and knowledge! Gracias! Danke Schonne! Thanks! Merci!
Very basic and easy to understand the concept. This is what I like for in a good teavher, someone who is able to put complex things into laymans terms. Thx for taking the time to make the video.
This lessons are much better than the ones on Sapling learning!! I watch my videos on there and I’m even more confused, I come here and DONE I get it !!! thank you guys!!!
Mr. Khan you really should talk about the dips between certain elements and their ionization energies because that is what most questions regarding this subject is asked... For the people who are wondering about this it is due to some elements having a valence electron in a lower energy subshell that is only half full as opposed to the following element having a full subshell. Thus a dip in energy needed for ionization.
holy shit... calculus videos AND you make chem videos?! dude, I should be paying YOU my tuition money for getting me through school since my junior year of h.s. up to now my freshman year of college.
@hockeymo due to the distance of this lonely electron from the nucleus coupled with the inner screening effect of the 3s and 2p6 orbitals for example, the protect the outer electron from the pull of the protons in the nucleus and so easier to lose :) hope that helps
@hockeymo Mg 1s2 2s2 2p6 3s2 1st I.E. = 736 kJ mol-1 Al 1s2 2s2 2p6 3s2 3px1 1st I.E. = 577 kJ mol-1 The 3p electron in aluminium is slightly more distant from the nucleus than the 3s, and partially screened by the 3s2 electrons as well as the inner electrons. Both of these factors offset the effect of the extra proton. basically while more electrons and more protons mean an increase in the attractive forces thus harder to REMOVE the electron across the period,
Do you have another video where you talk more about the factors affecting ionisation energy in more detail? I know u did mention atomic radii but ive noticed past paper questions ask about the factors affecting the ionisation energy going down a group and the overall trend etc. Thanks for the vid tho
Funny how everyone wants to replace their chem teacher with u and man i couldnt agree more .. She just makes us copy shit down and never explains shit.. Thanks man u r goin to save me on the unit test
Wallah. I swear to god and may allah bless you. Your amazing. My stupid arabian teacher teach like shit. And I come to you and ive under stood it better than the bastard at school. PLEASE KEEP MAKING MORE VIDS. Salam
***** It's offensive to mention "Allah" in a public commentary especially if you don't know his religion in addition I'm Christian so I know first hand myself how offensive it is... Don't want to burst your bubble nor upset you just throwing it out there but continue I don't mind. :/
I take it that the drops in ionization energies at elements like between Be-B, Mg-Al, Zn-Ga, Cd-In, Hg-Tl, etc can be explained by the fact that you're starting to fill a new p-shell, and so the electrons in the new shell are somewhat less tightly bound to the nucleus(?)... The same thing seems to happen between the d and f shells (Yb-Lu, No-Lr). But then why does that not happen after the transition between the s and d or f shells (Ca-Sc, Sr-Y, Ba-La)? Also, when filling the p-block, around N-O and P-S, it seems there is a slight drop in energy as you've filled about half that block... Does that have something to do with the electrons' spin? And if so, why is there not a similar drop for elements in higher periods (or for the halfway-filled d and f shells)?
@fosheimdet Because the first shell can only support two electrons, therefore with two electrons, it becomes stable. But from the second shell and on, the outer shell can support up to 8 electrons, and with 8 electrons, that atom becomes stable.
is it the electrons which decide the properties of the atom? Since you said that if Fluorine looses an electron it will become more like Oxygen? Anyways great series so far :D
The reason why you people learn better here is not due to your teachers inability to teach but your ability to learn in what circumstances so please dont insult your teachers, who probably tries their hardest to teach ,but you may not try your hardest to learn.
another mnemonic device for cation/anion: catabolic "breaks the electron# down or leaving a positive charge; whereas, anabolic builds up the electron # giving a net negative charge.
@NevadaEdW the more positive the ion is the less ionization energy it has and the more negative the ion is the more ionization energy it has.. so the order is: Se2- , Br- , Rb+ , Sr2+
LMFAO I IMAGINED SOMEONE TRYING TO IONIZE NEON AND THEN IT GOT ALL EMOTIONAL AND WAS LIKE "IV'E ACHIEVED HAPPINESS IN LIFE, DONT MESS WITH MY ELECTRON" LOOOOOOL
You are the best thing that has ever happened for science and math students.
Do u have an instagram?? 😅

This dude is better than my Chemistry teacher... Cheers!
you are amazing. seriously i could spend 10 minutes watching one of your videos and learn more than what my teacher would teach me in a 2 hour class.
Weren't you just teaching me calculus?
LOOOOOL
@Darwin Knox nope its a spam
Lol😅😅
Where have you been my entire academic career? THANK YOU!
This man just saved my life. Thanks so much sir youexplained a 2hrs concept in less than 12 minutes.
Please never stop making your videos. They really helped me a lot.
Thank you so much!
" You know what? I've achieved happiness in life, don't mess with my electron!" - Ne
LOL! Making that into a shirt would be amazing. XD As a home schooled high school student, thank you for making science so much easier to understand. :)
I'm on the first year of a Nutritional Therapy degree and the chemistry is killing me. You are making it so much easier, thank you very much indeed!!
And now you have a wife, congratulations, my gf left me after 5 years without saying why

cations are pawwwwwsitive
That's so cute and memorable!!
shutcho uglyass up
What's got you all in a hissy fit?
My teacher said pussytive
Does this guy teach everything?
no, otherwise you'd have the answer to that question
@@midbell wise
@@midbell LOL
@@midbell offf
He must be a passionate learner
Thank you so much, Sal! Your videos have been helping me all through high school. Really, I don't know where I'd be without them, thank you.
WOW! I loved your teaching! I just texted two of your videos on trends to all of my chemistry study pals. We are so grateful! Thanks a gazillion! You fill my outer shell with happiness and knowledge! Gracias! Danke Schonne! Thanks! Merci!

wow you've been helping me for about 4 years now with half of my subjects. i literally ow you my education.
Khan u are a life saver even after 11 years. THANK YOU
Wow , I used to hate chemistry because I couldn't understand any of it , but now it all makes so much sense!! Thank you Mr.Sal !!
This lessons are much better than the ones on Sapling learning!! I watch my videos on there and I’m even more confused, I come here and DONE I get it !!! thank you guys!!!
I have always found anything related to science INTENSELY boring. but khan academy has seriously saved my butt examination-wise. I LOVE YOU GUYS.
this is so helpful!!
can u actually believe i'm sitting in india studying this and i will totally ace my chem final!!!! thank u! :) :)

YOU'RE A LIFE SAVER OMG. I'M SOOOOO HAPPY I FINALLY GOT THE IDEA OF THESE TRENDS!!
8:26. Thank you for bringing this graph up. This answers so much.
knowing the stories about each group and period of elements is easier than memorizing the actual ionization trend : )
Thank you
You made gibberish sound human
😂😂😂
Best teacher on the internet.
khan is better than 1 3/4 of my enr chem course. and learned more in 1 hour than like a year
Your are brilliant , you put shame to those chemistry teacher that spend 3 hour explaining. You do it so effortless.
You are the sole reason I am passing chem. Thank you so much!
I'm going to update my facebook status.
"I've acheived happiness in life. Don't mess with my electron."
really helpful, i only wish many teachers were as effective at explaining as you :)
Thanks for saving my butt.
how can you explain something so well in 12 minutes what my teacher couldnt explain in 2 weeks.
loved what he said at 7:25 , understanding concept>>>memorization
i always thought fluorine would have a low ionization energy but now that you explained that it's really only cationization, i get it now
Wow, I would love for him to be my professor. He's so hilarious and I can actually understand it!
Thanx for bringing the Periodic Table to life! 🎉😊
holy shit... calculus videos AND you make chem videos?! dude, I should be paying YOU my tuition money for getting me through school since my junior year of h.s. up to now my freshman year of college.
Maaan. Your vids ARE THE BEST! thanx for explanining things your own way so we can understand it :D
This helped me so much! I understood this video better then my teacher =) Thank you
You are really goooooodddd at explaining
thank you. I would have failed my test tomorrow if it weren't for you
so how'd you do
should have watched this before my test thanks brother very helpful
You helped me more than my teacher could in a whole month
Thank you so much. You explained this so that it makes sense, as opposed to just memorization.
your the best you deserve an award for this program, you helped me a lot
LMAO....I'm 42....and yes I'm currently discussing Ionization Energy. What a funny and accurate reference!
'I've achieved happiness in life. Don't mess with my electrons!'
I love it =)
thankyou so much i think i might actually pass , you've given me hope :)!!!
@hockeymo due to the distance of this lonely electron from the nucleus coupled with the inner screening effect of the 3s and 2p6 orbitals for example, the protect the outer electron from the pull of the protons in the nucleus and so easier to lose :) hope that helps
Clear concept Very good video
GOD BLESS YOU SIR THANK YOU I CANNOT EXPRESS HOW HAPPY I AM RIGHT NOW THAT I UNDERSTAND IT THANK YOU THANK YOU THANK YOU
DAM! i dont even need to go to chemistry class anymore. all i need is just u!
Great way to remember this. Thanks!
THANK YOU VERY MUCH :)
very well explained.. it reminds me of my Chemistry teacher's style - fun and visual :D
2018 and this is still the only thing that’s gonna help me pass
sir you are an awesome teacher
Thanks helped a lot on my chem test
thank you so much Mr , everything now makes sense to me
This video really helped me. Thanks a lot.
Very good mnemonic right there!
wow this helps in my science class he gives us a worksheet and never tells what any of this means!
Thanks you!!!!! I have a Chem test tomorrow and this just saved my grade!! I UNDERSTAND NOW!!! :)
Thanks for all your help, Sal...can you make a video on electron affinity?...thanks
Wow, THANK YOU FOR EXPLAINING THIS.
So Neon and Lithium had a chat.
Lithium: I am so sad. I want to release my negativity.
Neon: I feel sorry for you. I'm happy and stable.
Cation = Positive charge because Cats(ions) are always positive! :D
Hi thanks for doing such a program it's a great help to me
Thank U a lot....
My concepts r now clear....
@hockeymo
Mg 1s2 2s2 2p6 3s2 1st I.E. = 736 kJ mol-1
Al 1s2 2s2 2p6 3s2 3px1 1st I.E. = 577 kJ mol-1
The 3p electron in aluminium is slightly more distant from the nucleus than the 3s, and partially screened by the 3s2 electrons as well as the inner electrons. Both of these factors offset the effect of the extra proton. basically while more electrons and more protons mean an increase in the attractive forces thus harder to REMOVE the electron across the period,
khan academy is the BEST

Its ok man, I know you hate muslims its ok who doesn't these days, and I will respect your thought, I wont say god anymore. Lol
this helped me remember how it goes thanks!

is it the electrons which decide the properties of the atom?

Great video! but a quick question. If Nobel Gasses do not have electronegative trends, how can the ionization levels in radon be lower than hydrogen?
another mnemonic device for cation/anion: catabolic "breaks the electron# down or leaving a positive charge; whereas, anabolic builds up the electron # giving a net negative charge.
Thank u so much. This helped a lot.
chemistry rule no.1: DONT MEMORIZE!
I will never forget how this trend works!
Thanks man ! 3:31am :D Finally understood this crap !
Brilliant ! Which video has stuff on bp/mp and atomic radii ?
live long and prosper. thank you
@NevadaEdW the more positive the ion is the less ionization energy it has and the more negative the ion is the more ionization energy it has.. so the order is:
Se2- , Br- , Rb+ , Sr2+
Thank you!! very helpful!
Very helpful!
Great video!!!
LMFAO I IMAGINED SOMEONE TRYING TO IONIZE NEON AND THEN IT GOT ALL EMOTIONAL AND WAS LIKE "IV'E ACHIEVED HAPPINESS IN LIFE, DONT MESS WITH MY ELECTRON" LOOOOOOL
Cation = ca(+)ion.... Positive
