We’re being asked to determine the electron configuration of Co2+ ion.
Before we can do that, we have to first write the electron configuration of a neutral ground state cobalt (Co).
You can determine the ground-state electron configuration of Cobalt (Co) by locating the position Co in the periodic table.
Ground-state means that the element is in its lowest energy form (not in excited state). Neutral barium means it has no charge, meaning no electrons are removed or added in the atom.
You see in the above illustration of the periodic table that Co is in Period 4 and d-block
Write the electron configuration for Co2+.
