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

What does Hund's rule states ?
