Hund's Rule, Pauli Exclusion Principle & Orbitals Diagrams

An electron occupies the lowest energy orbital that can receive it.

• Hund’s rule
• Pauli exclusion principle
• Bohr model of the atom
• Aufbau principle

All orbitals of equal energy are occupied by one electron before any single orbital is occupied by a second electron.

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.
