- TL;DR Summary
- Do the electron quantum numbers imply that those electrons are always in the corresponding eigenstates for those observables?

Going back to high school chemistry, i remember being taught that the electrons in an atom can each be identified with four quantum numbers - one for energy, two for angular momentum and one for spin. These numbers are integers except for the spin quantum numbers, which are either 1/2 or -1/2.

To me this seems to imply that at all times, every electron in an atom is in a state which is simultaneously an eigenstate for energy, total angular momentum, the angular momentum in the z direction, and spin.

Is this true, and if so why would that be the case?
