Front

What is the significance of the Aufbau principle in electron configuration?

Back

It states that electrons occupy the lowest energy orbitals first before filling higher energy levels.

What is Hund's rule in relation to electron configuration?

Back

Electrons will fill degenerate orbitals singly before pairing up.
