Understand the quantum numbers: n (principal quantum number), l (azimuthal quantum number), and ml (magnetic quantum number).
The principal quantum number n can be any positive integer (n = 1, 2, 3, ...). It determines the energy level of the electron.
The azimuthal quantum number l can be any integer from 0 to n-1. It determines the shape of the orbital.
The magnetic quantum number ml can be any integer from -l to +l, including zero. It determines the orientation of the orbital in space.
Evaluate each set of quantum numbers: Check if l is within the range 0 to n-1 and if ml is within the range -l to +l for each set.
