Pauli Exclusion Principle
A foundational principle of quantum mechanics, proposed by Wolfgang Pauli in 1925, stating that no two identical fermions within the same quantum system can occupy identical quantum states simultaneously. The principle serves as an essential theoretical basis for explaining atomic structure and the magnetic properties of matter.
