... The principal quantum number gives us the shell of the orbitals. This then gives the allowed values of (n – 1) which in turn describe the type of orbital (s, p, d, or f ). The m quantum number gives us the orientation of the orbital and its allowed values (– , – , + 1, . . . , – 1, ), which gives us ...
