Abstract: The paper expounds the origins of the four quantum numbers of electrons in an

atom and briefly presents the applications of the four quantum numbers: the electron shells of

an atom and the Pauli exclusion prin- ciple.

Key words: Bohr-Sommerfeld’s theory, four quantum numbers, electron shells, Pauli exclusion principle
