### Quantum numbers trick with angular momentum quantum number  [ENDORSED]

Its true that the number of orbitals which belong to a specific sub shell is specific to which "l" you are referring. For instance, the s-subshell has 1 orbital, the p has 3, the d has 5, and the f has 7. Using rate of increase (2 orbitals/change in l) and the initial value (1 orbital) you can simply devise the equation, 2l+1 to determine the total number of orbitals within a given sub shell. Remember that the s, p, d, and f sub shells are assigned l=0, 1, 2, 3 respectively.
From this you can deduce how many orbitals would occupy the next theoretical sub shell "g": 2(l=4) + 1 = 9 orbitals.

Certainly a useful expression, indeed.
