Ground states of ions Ground states of ions W Electrons are removed from the highest energy orbital first For the most part, that is the orbital that was just added to W Orbital energies depend on the configuration an unoccupied d-subshell is higher in energy than an occupied d-subshell the d-subshell and the s-subshell from the level about are very close in energy. Enough that when occupied, the d-subshell is lower in energy than the s-subshell W Order in s-d-p, order out p-s-d
