The 4s sublevel is only lower in energy if there are no electrons in the 3d sublevel. According to the
Aufbau principle, the 4s sublevel is filled before the 3d sublevel because the 4s is lower in energy.
As the 3d sublevel becomes populated with electrons, the relative energies of the 4s and 3d
fluctuate relative to one another and the 4s ends up higher in energy as the 3d sublevel fills. This is
why when electrons are lost from
