Question

Which quantum number is not required to describe an orbital wave function?

Answer 1

Explanation:

Rules Governing the Allowed Combinations of Quantum Numbers

The three quantum numbers (n, l, and m) that describe an orbital are integers: 0, 1, 2, 3, and so on.

The principal quantum number (n) cannot be zero. ...

The angular quantum number (l) can be any integer between 0 and n - 1.

The solution of this equation provides a set of numbers, called quantum numbers, which describe energies of the electron in atoms, information about the shape and orientations of the most probable distribution of electrons around the nucleus. These quantum numbers are the principal, azimuthal and magnetic quantum numbers but spin quantum is not associated with Schrodinger equation. The spin quantum number is associated with spin of the electron in doublets of the orbital.
