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.
