Re: Section 1D #25

the n=2 level would need to have 5 orbitals for 2d to exist, which is impossible as the only l values possible are 0 and 1. Therefore the largest ml range is -1 to +1 and the largest possible number of subshells at n=2 is 3. Hope that helps!

Re: Determining an orbital

I agree with all the above posts,
n describes the electron shell
l describes the subshell (when l is 0, S, when l is 1, P)
ml is the different orbitals of the subshell

Therefore l would determine 3s vs 3p . Hope that helps!
