... CONFIGURATIONS. The rules that govern the way the electrons fill the atomic orbitals are: 1. AUFBAU PRINCIPLE - electrons enter orbitals of the lowest energy levels first 2. PAULI EXCLUSION PRINCIPLE - an atomic orbital may hold at most two electrons. Each must have an opposite spin. 3. HUND’S RULE ...
