When determining the principal and orbital angular quantum numbers, you must keep in mind that n (the principal quantum number) corresponds with the energy level {1,2,3...} and that is given in the beginning of the number. The l (the angular quantum number) corresponds to the number associated with the orbital (s-0, p-1, d-2, f-3).
