What are the allowed values for quantum numbers?
Rules Governing the Allowed Combinations of Quantum Numbers The principal quantum number (n) cannot be zero. The allowed values of n are therefore 1, 2, 3, 4, and so on. The angular quantum number (l) can be any integer between 0 and n – 1. If n = 3, for example, l can be either 0, 1, or 2.
What quantum numbers sets are not allowed?
The spin quantum number is +1/2, which is allowed. Because this set of quantum numbers follows all restrictions, it is possible. The quantum number n is an integer, but the quantum number ℓ must be less than n, which it is not. Thus, this is not an allowed set of quantum numbers.
