Electron Configuration Rules: Aufbau & Pauli Exclusion Principle, Hund's Rule

This video tutorial explains the three fundamental rules for writing electron configurations: the Aufbau principle, Hund's rule, and the Pauli exclusion principle. The Aufbau principle states that electrons fill lower energy levels first. Hund's rule emphasizes that electrons prefer to be unpaired in orbitals when possible. The Pauli exclusion principle requires that electrons in the same orbital have opposite spins. Understanding these rules is crucial for correctly writing electron configurations.
