The Quantum Numbers
... The fact that each electron in an orbital must have different spin quantum numbers led Wolfgang Pauli to the conclusion that no two electrons in the same atom can have the same four quantum numbers. This conclusion still holds true and is known as the Pauli Exclusion Principle. ...
