Sample Question
What is Hund's rule?

Electrons will always occupy the lowest energy level available.

Electrons will pair up in the same orbital only when all orbitals have at least one electron.

Electrons will fill orbitals of the same energy level one at a time with parallel spins before pairing up.

Electrons will populate higher energy orbitals before filling lower energy orbitals.
