Electrons occupy orbitals of lowest energy first is part of what electron configuration rule?

• Hund’s Rule

• Aufbau Principle
  

• Pauli Exclusion Principle

What does Pauli exclusion principle state ?

• states that each electron occupies the lowest energy orbital available

• states that a maximum of two electrons can occupy a single atomic orbital, but if only if the electros have opposite spins

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