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 is incorrect about this orbital diagram?

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

• There is nothing incorrect with this diagram

• 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.
