Pauli exclusion principle electrons in a single atom occupy discrete levels of energy no two “energy levels” or “states” in an atom can have the same energy. Aufbau principle: lower energy orbitals fill before higher energy orbitals hund's rule: one electron goes into each until all of them are half full before pairing up. The pauli exclusion principle is the quantum mechanical principle that states that two or more identical fermions (particles with half-integer spin) cannot occupy the.
(atomic physics) physics the principle that two identical fermions cannot occupy the same quantum state in a body such as an atom sometimes shortened to: exclusion.
