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

• Hund’s Rule

• Aufbau Principle

• Pauli Exclusion Principle

What is incorrect about this orbital diagram?

• Both arrows in the 2p box should be pointing up

• There is nothing incorrect with this diagram

• In the 2p box there should only be 1 electron in the first 2p box and one in the 2nd 2p box

• All the arrows should be pointing up.
