What is Hund's rule?
What is Pauli Exclusion principle?
The Hund's rule states that electrons will occupy their own sublevel orientation before sharing one with another electron.
The Pauli Exclusion principle states that no two electrons can occupy the same spin. One must go op and one must go down.
