ChemTeam: Quantum Numbers
There are four quantum numbers; their symbols are n, ℓ, mℓ and ms. EVERY electron in an atom has a specific, unique set of these four quantum numbers. The story behind how these numbers came to be discovered is a complex one indeed and is one best left for another day.[PDF]
