Atoms Quote by Wolfgang Pauli

“There can never be two or more equivalent electrons in an atom, for which in a strong field the values of all the quantum numbers n, k1, k2 and m are the same. If an electron is present, for which these quantum numbers (in an external field) have definite values, then this state is 'occupied.'” quote by Wolfgang Pauli

About This Quote

Source Scientific Paper: Pauli Exclusion Principle, 1925

No two electrons in an atom can share the same set of quantum numbers; each electron occupies a unique state.

In simple terms: Each electron must have a distinct set of quantum numbers.

Key Takeaway

Recognize and respect individual uniqueness.
