Question

Can anyone please help me understand electron configuration/quantum number stuff??? ... I do NOT understand this at all. So it ways what is the electron configuration of Kr? ..... I have the answer(s) ..but I just don't know what they're talking about or have a clue how to figure this out on my own. Please explain?

Answer 1

there are tons of videos on youtube, like this one
http://www.youtube.com/watch?v=oK6K68ADKDA

if you have a more specific question i can try to answer it

Answer 2

Thanks @aaronq. I appreciate it a bunch. I'm just really confused & it seems really easy =/

Answer 3

Well that video didn't really help me. :( Hopefully my teacher can help me on Monday.

Answer 4

question is not clear
where you are not understanding

Answer 5

Pretty much everything about how to figure anything out using quantum numbers?? I don't know... I understand what there and what they mean .. but then in the notes it says what is the electron configuration of Kr? The answer is \[1s ^{2}2s ^{2}2p ^{6}3s ^{2}3p ^{6}4s ^{2}3d ^{10}4p ^{6}\] ...? I don't know where the answer comes from

Answer 6

quantum numbers u are not getting
see there are some rules and way to do this all stufff
u should learn those basic things
did you?

Answer 7

Yeah, but I don't understand it. :(

Answer 8

using quantum numbers u assign electrons address

Answer 9

where exactly is the electron from the nucleus

Answer 10

1S2 in this case
1 is prinicpal quantum number (shell)
S is angular quantum number(subshell)
super script 2 indicates no of electrons in that subshell

Answer 11

1(also called K) shell has s subshell
2 (also called L)shell has s and p subshell
3 (also called M)shell has s , p and d sybshell
4 (also called N )shell has s, p ,d ad f subshell

Answer 12

this may help you

Answer 13

s subshell will have only 2 electrons
p -6electrons
d-10 electrons
f-14 electrons

Answer 14

i thin u r not getting me

Answer 15

based on the atomic no of Kr u have two write it

Answer 16

I'll check out the site... It seems like this should be really easy and I wish I wasn't so confused!!!

Answer 17

yaaa its very easy if u understand it once

Answer 18

Hopefully it will click before my test this next Thursday!!! I've been trying to figure it out all day!!
