### Problem ID.11

How do you figure out how many orbitals are subshells with l equal to a specific value?

re: How do you figure out how many orbitals are subshells with l equal to a specific value?

I am a little confused by your question. However l is the essentially and value less than the n and greater than or equal to 0. For example if n=3 then l can be 0,1 or 2. Inside sub shells are orbitals. For example for the 2p sub shell there are three orbitals.

To figure out how many orbitals are in a sub shell l: # = 2l +1

The "l" quantum number distinguishes the sub shell (0=s 1=p 2=d 3=f)
Each sub shell has a set number of orbitals which I like to think about visually but they also increase by two each sub shell
s has 1
p has 3
d has 5
f has 7 and these are all denoted by the 3rd quantum number which ranges from -l to l with all integers in between

for example if you are given

n=3 l=2 you have 5 options for ml -2,-1,0,1,2 and of course 2 options (-.5 and +.5) for ms
