WebHund's Rule #3. For atoms with less than half-filled shells, the level with the lowest value of J lies lowest in energy. Example: Since p 2 is less than half-filled, the three levels of 3 P are expected to lie in the order 3 P 0 < 3 P 1 < 3 P 2 . When the shell is more than half full, the opposite rule holds (highest J lies lowest).
