Thank you so much for this video. I have a chem test in two days about all the periodic trends and I missed one day due to being ill so i missed this lesson. I heard my teacher explain it a bit but I couldnt fully understand. This helped so much!
thanks im currently revising chemistry and came across the definition of electronegativity but didnt understand it but i have now thanks to this video big thumbs up 👌
If a molecule has lone pairs of electrons, it's polar. Otherwise it's non-polar. In water, oxygen has 2 pairs of lone electrons, and so it is classified as polar.
Thanks so much for your videos - your explanations are well constructed, paced and they're mentally accessible. I really appreciate all you've done in the past years!
thank you! peace out!i know oxygen for sures is highest electronegativity ! cool I was oxygen for my Halloween costume. I loved oxygen and now I love it even more! I understand that going down row 1 sublevel as you get to sublevel two , three, four etc the electronegativity gets less. The least amount of electrons a element has it is more likely to give away an electron . the elements that are closest to completing their octet will want to gain take from other elements to have a full octet. cool beans
That's of course as a general rule, but there're serious flaws: He can be more electronegive than Li, given how many electrons each one has and how short they may be in electrons in their environment... so like a lot in chemistry, it stands as iffy. And it *ought* for if all electrons had been filled into atoms and all atoms had the balanced amount of electrons, then really very few chemical reactions could possibly happen. In short, it is partly due to the imbalance between electrons and protons that chemistry works the way it does.
What I don't like about these videos is the guy repeats himself way too many times, so much I forget what his point of explanation is. Like just shut up and right it out, stop sounding out everything you write lol.
i prefer it it cuz its like he is kinda stressing the point so it sticks more into my head but we are all different lol but i do agree he should write everything out.
You do know that this guy was kind enough to create a whole comprehensive online school where people from around the world can learn for free, right? Who are you to criticize and what have you done for society? You should be grateful even if you have benefited from this video only a little. He has changed the world of online learning.
Well, about the periodic table: you would be getting more electronegative as you go towards your right while looking at the table facing properly; with the exception of the noble gases: those guys are perfectly balanced about electrons and protons as a rule.
Well, electrons would be zipping all over the place around the nucleus of the atom in three-dimensions, so it would be seen as a blur; why wouldn't it? They'd be moving incredibly fast and are very miniscule, and atoms are almost entirely empty space to begin with.
So, Mr. Khan; astronomy *is* in fact a good and functional lens for atomic chemistry in that the further away an electron is from its nucleus the more likely it is to be snatched away, whereas this is similar to planets and stars- but it is a *very* limited analogy.
3:47 "electrons are in this kind of blur [...]" i.e., Heisenberg's Uncertainty Principle and the probability cloud of where they can be found at any given moment. The probability cloud can be calculated as a wave form with the de Broglie wavelength, I think? Great video, thank you!
So, this really means that these atoms positive charge is being measured, the greater the electronegativity present the more the positive charge thereof.
Is it possible to make a noble gas more reactive by bombarding it with radiation such as alpha particles or positrons? My reasoning is that the mentioned forms of radiation could rip valence electrons away from the noble gases, turning them into ions. Is this a valid idea?
when you learn more in a 10 min vid than a whole semester worth of work ............
Vedant Subramanian on god
Oh yeah yeah
My teacher is so useless
@Cheewe Tell that to my 8th science teacher who gave us all hands on activities and actually taught us unlike a lot of teachers.
SourLem0n you shouldn’t say what if someone else says that about your parents
god i hate chemistry
I hate chemistry but love physics
more than physics chemistry easy bro
the explanation is confusing that's it . this concept is easy
Daesung Mars because you are a fool
Ishaan Manu chill out mahn
Thanks i missed some classes and suddenly i didnt know ehat was going on this realy helped and made it easy to understand
Because noble gases are just happy! haha!
Thanks this helps a lot for AP Chem!
just shut up

You are the best. Thank you very much. May the good Lord Bless you 🙏
Thank you, this video was very helpful :)
Thank you so much for this video. I have a chem test in two days about all the periodic trends and I missed one day due to being ill so i missed this lesson. I heard my teacher explain it a bit but I couldnt fully understand. This helped so much!
thank you sir for such a goof explanation
straight and easy to understand than textbooks!
thanks im currently revising chemistry and came across the definition of electronegativity but didnt understand it but i have now thanks to this video big thumbs up 👌
Thank you so much! Your videos are always super helpful!
This video really helped me, thank you !
this helped. Now I understand why that is more electronegative going up.
How do you know the value of the electronegativity?? So you can know if a molecule is polar or no polar
Look at the trends! They are right almost every time. Also, you can see them in most periodic tables!
If a molecule has lone pairs of electrons, it's polar. Otherwise it's non-polar. In water, oxygen has 2 pairs of lone electrons, and so it is classified as polar.
Great video! Thank you so much :)
dude i thought i nevr cd undrstand these..but u made me do it in a jiffy
How old are you
Vrushali Ramila shut up vvvvv
So this is why the column of 1A from Soduim to Cesium is so reactive. And that Cesium practically explodes when you throw it in water.
Antropovich You should see francium when you throw it in water
very very clear. thank you sir
The one concept that my teacher didn't explain well. Thanks!
Thanks so much for your videos - your explanations are well constructed, paced and they're mentally accessible. I really appreciate all you've done in the past years!
thanx for explaining the trend of electronegativity,thanx a lot again
great refresher.... AWESOME JOB!!!
....
most helpful study chanel
Do have to repeat what you write like a gazillion time.
Btw amazing videos got me through my exams.
Burhanuddin Salim lmao
This is like a life lesson. Love it.
So, what we really should think of measuring in this is the quantity of protons and the closeness of the protons and the electrons above all, eh?

Nicely explained sir. Thank you!
Cool edit on the profile pic, bruh.
+LeChat Noir its no edit its legit mate #legit #saynotosteriods #hardwork
me not paying attention to this video tha I am watching because I wasn't paying attention in class... I'm probably gonna fail chemistry
thanks ! excellent explanation !
Thanks!
this is very helpful God bless Khan Academy
Thanks
thanx for making chemistry easy
like this very much.

awsome
I don't understand why h2o has 6 valence electrons.... Like what the hell? And how does Li have a .98 electronegativity?
That's of course as a general rule, but there're serious flaws: He can be more electronegive than Li, given how many electrons each one has and how short they may be in electrons in their environment... so like a lot in chemistry, it stands as iffy.

How am I supposed to remember this... my test isn’t open note
aren't there any exceptions
White page.. 😑
Nice jay hind🇮🇳🇮🇳
Should cut off the unecessary explanation. Other than that everything is good :)
Extra knowledge never hurts :)
it always hurts

right I agreee
then go somewhere else brah
i prefer it it cuz its like he is kinda stressing the point so it sticks more into my head but we are all different lol but i do agree he should write everything out.
Some people might be a little slow, they may not be as smart as you. So be patient and let everyone learn.

I think the guy repeats his sentenses because he himself forget what he recently said in last lines... Lol
Would you like a job in Ireland?
My boring Chemistry teacher would love to be anywhere else.
This helped me so much, thank you!!
Thanks
awsome
This video helped so much. My teacher sucked at explaining it! Thanks dude!
Really...
If you wrote textbooks.....
It would be an e-book, with pictures translated via spectrogram.
they'd be endorsed by the British education system
WHERE WAS THIS WHEN I WAS AN UNDERGRAD?!?
Maybe your context was kinda outdated.
Wowwwww.....great explanation..... Tq so much for the video
Well, about the periodic table: you would be getting more electronegative as you go towards your right while looking at the table facing properly; with the exception of the noble gases: those guys are perfectly balanced about electrons and protons as a rule.
thanks man, really helped
This video couldn't have been any better. Thanks!

I never understood the group trends but now I do thanks to you

Great video, thank you!
Electronegativity (Withdraw a electron in Molecular state): F > O > N > Cl
Electron Affinity (Withdraw a electron in Atomic state): Cl > F > Br > I
It is more like F>O>N=Cl
Mehul Jain Tiebreaker, N> Cl due to smaller atomic size
thanks
What is the Electronegativity value of Iodine gas?
Its 2.5, the electronegativity also decreases going down group 17
Thanks, love you Sal.
0:08 ayo 💀💀💀
Yeah close lmao
It is cool when your first language is spanish and you are studing chemistry in english
Fantastic video, thank you!
Awesome
So, this really means that these atoms positive charge is being measured, the greater the electronegativity present the more the positive charge thereof.
Why is there not translation for Indonesian? And i hope someday there will be a translation for Indonesian.
That was a great video ty sir
Noble gases are very happy.
thank you very much helped me understand these easily! keep up the good work
i prefer video black background
Wow thanks for the great video. Bless your soul
Which is more electronegative, N or Cl?
Cl
N. In NCl3, the computer modellings show the negative charges are residing on the N atom. Even carbon bears a negative charge in CCl4.
What exactly is the formula
doesnt oxygen have 8 electrons...
Ionas Finser Lol?
Exactly! Where’s the other 2 electrons?
u r my fav khan. TY FOR MAKING VIDEOS SO GOOD.😁👌
because they're just happy😀
Thanks a lot man u r a proper legend! Keep doing what you do coz u r getting through my freakin O' Levels! xDD
Ayaan Danish I got through mine with these videos.... Now working towards my AS with them again

this Video is one of the best videos i EVER seen among all scientific disciplines , WOOOOW
💜💜💜💜
Thank you so much!
I hate AP bio so much
Just wondering where in the video you talk about Electron Affinity?
Have some modern style periodic table looks old
