What do quantum numbers describe?
The energy level, shape of orbital, orientation of the orbital and the spin of an electron, for a given electron.
The quantum numbers are represented as:
It tells whether a electron is spin-up or spin-down.
The video below explains how quantum numbers describe the position of an electron. The video also discusses how to determine the quantum numbers for four different electrons (#1, 6, 29).
