Front

Electrons occupy orbitals of lowest energy first is part of what electron configuration rule? Options: Hund’s Rule, Aufbau Principle, Pauli Exclusion Principle

Back

Aufbau Principle

Front

What does Pauli exclusion principle state?

Back

States that a maximum of two electrons can occupy a single atomic orbital, but only if the electrons have opposite spins.

Front

What does Hund's rule state?

Back

states that single electrons with the same spin must occupy each-energy orbital before additional electrons with opposite spins can occupy the same orbitals
