Electronegativity is a measure of an atom's ability to attract shared electrons to itself. On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group. As a result, the most electronegative elements are found on the top right of the periodic table, while the least electronegative elements are found on the bottom left.

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
This video helped so much. My teacher sucked at explaining it! Thanks dude!
Really...
Would you like a job in Ireland?
My boring Chemistry teacher would love to be anywhere else.
If you wrote textbooks.....
It would be an e-book, with pictures translated via spectrogram.
they'd be endorsed by the British education system
Wowwwww.....great explanation..... Tq so much for the video
WHERE WAS THIS WHEN I WAS AN UNDERGRAD?!?
Maybe your context was kinda outdated.
Because noble gases are just happy! haha!
Thanks this helps a lot for AP Chem!
just shut up
@@imaazillyas1122 f u 2
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 i missed some classes and suddenly i didnt know ehat was going on this realy helped and made it easy to understand
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
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.
Thank you, this video was very helpful :)
You are the best. Thank you very much. May the good Lord Bless you 🙏
Thanks ❤️❤️❤️
This video couldn't have been any better. Thanks!
Definitely passing my pharmacy cat after watching this

So, this really means that these atoms positive charge is being measured, the greater the electronegativity present the more the positive charge thereof.
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.
It is cool when your first language is spanish and you are studing chemistry in english
9:38 what some people might be looking for
What is the Electronegativity value of Iodine gas?
Its 2.5, the electronegativity also decreases going down group 17
Thank you! You're the best!
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.
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
thank you sir for such a goof explanation
straight and easy to understand than textbooks!
White page.. 😑
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
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!
I never understood the group trends but now I do thanks to you
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?
Thank you so much! Your videos are always super helpful!
Thanks
thanks
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
Thanks, love you Sal.
Do have to repeat what you write like a gazillion time.
Btw amazing videos got me through my exams.
Burhanuddin Salim lmao
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 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!
Should cut off the unecessary explanation. Other than that everything is good :)
Extra knowledge never hurts :)
it always hurts
8 likes for everyone-fight!
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
u r my fav khan. TY FOR MAKING VIDEOS SO GOOD.😁👌
0:08 ayo 💀💀💀
Yeah close lmao
Fantastic video, thank you!
this helped. Now I understand why that is more electronegative going up.
thank you very much helped me understand these easily! keep up the good work
Noble gases are very happy.
doesnt oxygen have 8 electrons...
Ionas Finser Lol?
Exactly! Where’s the other 2 electrons?
Legend
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
Wow thanks for the great video. Bless your soul
Great video! Thank you so much :)
Awesome
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.
i prefer video black background
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?
What exactly is the formula
Why does hydrogen stick close next to other hydrogen
I don't regret subcribing to your channel.
This video really helped me, thank you !
because they're just happy😀
this Video is one of the best videos i EVER seen among all scientific disciplines , WOOOOW
very very clear. thank you sir
Why is there not translation for Indonesian? And i hope someday there will be a translation for Indonesian.
The one concept that my teacher didn't explain well. Thanks!
I don't understand why h2o has 6 valence electrons.... Like what the hell? And how does Li have a .98 electronegativity?
That was a great video ty sir
💜💜💜💜
Just wondering where in the video you talk about Electron Affinity?
most helpful study chanel
like this very much.
This helped me so much, thank you!!
why is this video in two times for the SAT Chem Subj playlist?
How am I supposed to remember this... my test isn’t open note
thanx for explaining the trend of electronegativity,thanx a lot again
Nicely explained sir. Thank you!
Cool edit on the profile pic, bruh.
+LeChat Noir its no edit its legit mate #legit #saynotosteriods #hardwork
Thank you so much!
Nice jay hind🇮🇳🇮🇳
How does Na have 1 electron in it's outer shell if the atomic # is 11? Isn't it supposed to have 11 electrons since protons and electrons are supposed to be balanced?
Rene Willy Lol you find out valence electrons by group number not by atomic number
my guy, sodium has more than one shell. it has 2 in the first shell, 8 in the second, and 1 in the outer shell. they add up to 11.
Can someone summarize this video in 4-5 sentences??
No.
elements which are closer to inert gases are most electro-negative. boom.
Have some modern style periodic table looks old
I hate AP bio so much
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!
Thanks!
great refresher.... AWESOME JOB!!!
....
The distance of 'N' and 'Br' is same from 'F'..So this, are their electronegativities same??
the one that is higher up which is N
masum biswas F > O > N > Cl > Br
But which atom is more electronegative? Carbon or phosphorus?????
Late response but phosphorus
thanks ! excellent explanation !
Hey you used the Lewis dot structure :)
thanx for making chemistry easy
aren't there any exceptions
awsome
Thank you sooooooooooooomuch.
Cool presentation :D
Too much detail, needs to keep it simpler.
THANK YOU
I think the guy repeats his sentenses because he himself forget what he recently said in last lines... Lol
this is very helpful God bless Khan Academy
