Front

What is the significance of the Aufbau principle?

Back

The Aufbau principle states that electrons occupy the lowest energy orbitals first.

Front

What is the Pauli Exclusion Principle?

Back

The Pauli Exclusion Principle states that no two electrons in an atom can have the same set of four quantum numbers.
