Thanks! He started off criticizing Sal for not being able to name an element when he hasn’t contributed a thing to Youtube so I told if he doesn’t like these vids to go back to sleep and that’s where the drama began.
@jumb0mumb0 dude forget about him, he’s clearly retarded…
@calabarbean
“Don’t mess with me!” I already did, idiot. If you were a bug, i’d dissect you into thousand different pieces you pathetic sack of shit.You are clueless about elementary science, let alone chemistry.
@jumb0mumb0 Told you retard: Don’t mess with me ! I know way more chemistry than you do. I’ve searched this video for my 16 years old kid so he could learn sth. And it is instructive, however it is not acceptable for khan not to know the name of elements !!
So again: Go fuck yourself
@calabarbean
You don’t even belong in a discussion for a video on chemistry. With your degree of intelligence and lack of a sophisticated vocabulary, you belong in a prison cell with all the other inmates who may show signs of attraction toward you! Or better yet, enslaved to a low paying job where the employees have nothing better to do than swear. Do us a favor and go back to sleep!
@jumb0mumb0 Go fuck yourself retarded
@calabarbean
Do us a favor and go back to sleep then!!
please make some examples for the f-group, i don’t get why Uranium has [Rn] 5f3 6d1 7s2 and Plutonium [Rn] 5f6 7s2. What happens with that 6d1 ? o.o
LOL !!!! You don’t even know the name of the elements??? And you wanna teach us??
What a shame Khan…
Do you have anything on quantum numbers and energy required to to move to another energy shell? I am studying Chemistry.
haha tin haha
@Giallorossi03 Lol “silinium”…..it’s Selenium
@PINKmeUP67 It’s 7 because the highest energy level is 4. [Ar]4s2 3d10 4p5
The 4s2 and the 4p5 add to 7.
That 3d10 portion is what he was talking about when he mentioned the back filling. Make sense?
Finally, I am getting this. Thank you Dr. Khan!
when i write an electron configuration in noble gases, how do i know how many valence electrons there are? for example [Ar] 4s2 3d10 4p5 has 7 valence electrons. how does that work?! wouldn’t it be 17?
This video helped me so much thank you!
thats a pretty flower you drew
I don’t understand how to write that stuff in the beginning. How do you determine those numbers and letters…like what are you looking at to know that?
@Giallorossi03 you guys…the periodic table consist of elements that are named in Latin and Greek. Tin is the English notation for this element. But yeah, it is kinda funny =D
All halogens are greedy bastards.
@ligitcounterfit no he meant to say as the atom gets larger
Dear Prof. Khan, is it possible to write Fe as [Ca]3d6? or would it be better to write it as [Ar]4s23d6 since it shows that 4 is the highest energy shell?
lol “if you dont trust me..” Dear Khan we will believe anything you say
would be n1 if you add numbers to the video, to see which video is the next etc.
hydrogen and helium are 2 happy elements
