* See Miss Nelson for correct answer
1. Aufbau Principal: Each electron occupies the lowest energy orbital available.
2. Pauli Exclusion Principal: A max of 2 electrons can occupy a single orbital.
3. Hund's Rule: Single e- with the same spin must occupy each equal energy orbital before additional e- with opposite spins can occupy the same orbital.
