Which from following rule / principle states that "No two electrons in an atom can have the same set of four quantum numbers"?
Pauli's exclusion principle
Hund's rule
Aufbau rule
Heisenberg uncertainty principle
Solution
The Pauli Exclusion Principle states that no two electrons can occupy the same quantum state, which explains the filling order of atomic shells in the periodic table.
