(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The number of electron states in a subshell with orbital quantum number l = 3 is:

A. 7

B. 9

C. 14 <-- answer

D. 2

E. 3

I am reviewing for a comprehensive final and maybe its all the studying but I am lost here..

2. Relevant equations

n=/=0

l= 0--> (n-1)

m = -l to l

3. The attempt at a solution

Okay so far I have that if l = 3 then m = [-3,...,3] and that n= 4. Do I just add them up 3+7+4 to arrive at the answer? Is this representative of the different combinations? Orbitals are the one subject I consistently have difficulty with in chem/phys. Thanks for your help.
