"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. :)
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!
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.
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!
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!!!
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.
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)?
@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
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
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. :/
If you have an element that is in a lower row, but is more to the right in the table...Which would have the larger ionization energy? For example, Se and Si...
@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+
I feel guilty - I completely skipped electron config 2 and valence electrons because the shells and stuff were completely getting away from me. Is it absolutely necessary to understand SPDF shells?
@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,
Why is it low to high for the transition metals? Don't they all only have two valence electrons? In addition, if copper has a higher reserve of electrons in its d-shell than nickel, won't it be more likely to give electrons away, making its ionization energy less than that of nickel?
@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.
Calcium has a much lower Ionization energy level because it's only located in the 2ND group, which means that they have 2 electrons in there outer shell that they want to give away so they can reach a stable state. Also, the trends in the p.table show that the elements with the highest ionization energy are located in the TOP LEFT, and the lowest are located in the BOTTOM RIGHT, again this is because of the amount of electrons in their outer shell and their "willingness" to give away electrons even when it means that they will take a step back in the journey to a stable atom with 8 electrons in each shell
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.
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
"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.'"

This dude is better than my Chemistry teacher... Cheers!
Weren't you just teaching me calculus?
LOOOOOL
@Darwin Knox nope its a spam
Lol😅😅
Does this guy teach everything?
no, otherwise you'd have the answer to that question

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. :)
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.
Please never stop making your videos. They really helped me a lot.
Thank you so much!
Where have you been my entire academic career? THANK YOU!
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.
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!
This man just saved my life. Thanks so much sir youexplained a 2hrs concept in less than 12 minutes.
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 !!

wow you've been helping me for about 4 years now with half of my subjects. i literally ow you my education.
Thank you
You made gibberish sound human
😂😂😂
8:26. Thank you for bringing this graph up. This answers so much.
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! :) :)
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
@@dddaaa6965 L
knowing the stories about each group and period of elements is easier than memorizing the actual ionization trend : )
You are the sole reason I am passing chem. Thank you so much!
thank you. I would have failed my test tomorrow if it weren't for you
so how'd you do
Thank you so much. You explained this so that it makes sense, as opposed to just memorization.
really helpful, i only wish many teachers were as effective at explaining as you :)
Thanks for saving my butt.
you make it all make sence thankyou so much for uploading your videos
You are really goooooodddd at explaining
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 video really helped me. Thanks a lot.
This helped me so much! I understood this video better then my teacher =) Thank you
Thanks for all your help, Sal...can you make a video on electron affinity?...thanks
Maaan. Your vids ARE THE BEST! thanx for explanining things your own way so we can understand it :D
thank you so much Mr , everything now makes sense to me
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
Your are brilliant , you put shame to those chemistry teacher that spend 3 hour explaining. You do it so effortless.
Thanx for bringing the Periodic Table to life! 🎉😊
loved what he said at 7:25 , understanding concept>>>memorization
THANK YOU VERY MUCH :)
very well explained.. it reminds me of my Chemistry teacher's style - fun and visual :D
Hi thanks for doing such a program it's a great help to me

should have watched this before my test thanks brother very helpful
Does the energy change depending on the state of matter ie solid or gaseous
Clear concept Very good video
LMAO....I'm 42....and yes I'm currently discussing Ionization Energy. What a funny and accurate reference!
how can you explain something so well in 12 minutes what my teacher couldnt explain in 2 weeks.
Brilliant ! Which video has stuff on bp/mp and atomic radii ?
Wow, I would love for him to be my professor. He's so hilarious and I can actually understand it!
Thank U a lot....
My concepts r now clear....
Great way to remember this. Thanks!
So could you also say that the ionization energy is the amount of resistance an atom has to remove its electrons?
this helped me remember how it goes thanks!
is this process or the principle of the aurorae borealis?
Is ionization energy of carbon more or less as it has 4electrons in its valence which is mid way
Thank you !! This video helped so much
thankyou so much i think i might actually pass , you've given me hope :)!!!
Do we need to remember the whole periodic table for class 11& 12
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
You helped me more than my teacher could in a whole month
Best teacher on the internet.
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?
@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
pls,why didn't u arranged the second equation like the first?
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
Amazing as always! Thank you
sir you are an awesome teacher
Wow, THANK YOU FOR EXPLAINING THIS.
DAM! i dont even need to go to chemistry class anymore. all i need is just u!
khan is better than 1 3/4 of my enr chem course. and learned more in 1 hour than like a year
Thanks for the explanation!
'I've achieved happiness in life. Don't mess with my electrons!'
I love it =)
Thank you soooo much! this was a huge help.
2018 and this is still the only thing that’s gonna help me pass

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.

Does Rubidium have high ionisation energy than Lithium? Please help me
I feel guilty - I completely skipped electron config 2 and valence electrons because the shells and stuff were completely getting away from me. Is it absolutely necessary to understand SPDF shells?
