Can someone please explain why Sc+2 and potassium don't have the same valence shell electron configuration?

The e- config for K is [Ar]4s1 while for Sc^(2+) it is [Ar]3d1. This is because Sc normally is [Ar]3d1 4s2 but when you ionize this and take away 2 electrons you first have to ionize the 4s orbital and then, if necessary, the 3d orbital. This is because the 3d orbital becomes of less energy than the 4s orbital after it begins to fill with electrons.

Although Sc2+ and K have the same number of electrons, their electron configurations are different and that is why they don't have the same valence shell electron configuration.
