Front

What is the Aufbau principle?

Back

Electrons occupy the lowest energy orbitals first.

Front

What is Hund's rule?

Back

Every orbital in a sublevel is singly occupied before any orbital is doubly occupied.

What is the Pauli Exclusion Principle?

Back

No two electrons in an atom can have the same set of four quantum numbers.
