State the four quantum numbers and what each describes.
Original Khojo Papers practice question — not from a past board paper.
Answer
The principal quantum number n gives the shell and the main energy level. The azimuthal quantum number l gives the subshell and the shape of the orbital. The magnetic quantum number m gives the orientation of the orbital in space. The spin quantum number s gives the direction of spin of the electron.

Explanation
No two electrons in an atom may have all four the same, which is the Pauli exclusion principle.
