That gives you the correct electron configuration, argon 4s 2, 3d 1. But it's implying that the d orbitals, the 3d orbitals fill after the 4s orbital and is therefore a higher energy and that's not true actually. It does help you to just assume that's the case if you're writing an electron configuration but that's not what's happening in reality.
For the alkaline earth metals the valence s orbital is filled, and so an additional electron would have to go into a p or d orbital, which are higher in energy. So the electron affinity for the alkaline earth metals is expected to be positive. 58) Write the ground state electron configurations of the following ions: a) Li+ 1s2 = [He] b) H- 1s2 ...
Oxygen, for example, has the electron configuration 1s 2 2s 2 2p 4, whereas the oxygen anion has the electron configuration of the noble gas neon (Ne), 1s 2 2s 2 2p 6. The two additional electrons required to fill the valence orbitals give the oxide ion the charge of 2– (O 2– ).
