### Quantum Numbers and subshells

Posted: Sun Nov 03, 2019 10:11 am
Hello,

I have a question about what subshells "l" numbers are. For example if n=3, then l = 0, 1, 2 or basically l = 0,1,2...n-1. Then if n = 5, then l = 0,1,2,3,4 right?
So if an "l" value of 0 corresponds to the "s" subshell, 1 corresponds to the "p" subshell, 2 corresponds to the "d" subshell, and 3 corresponds to the "f" subshell right? So if n = 5, according to the possible values of "l = 0,1,2,3,4" what is the l = 4 subshell called and where on the periodic table is it in (like there is an "s" block, a "d" block, an "f" block and a "p" block)?

Thank you!

I don't think we have to know anything other than the s, p, d and f orbitals so I wouldn't worry too much about it!

I think that for the purposes of this class we only cover the quantum numbers from l=0,1,2,3, 0 being s, 1 being p, 2 being d, and 3 being f. We don't really talk about the g and h, etc. subshells so we only go to l=3.
