We’re being asked to determine why is the Ru3+ electron configuration [Kr] 4d5 5s0 instead of having a full s orbital

Before we can do that, we have to first write the electron configuration of a neutral ground state Ruthenium (Ru).


You can determine the ground-state electron configuration of Ru by locating the position Ru in the periodic table.

Ground-state means that the element is in its lowest energy form (not in excited state). Neutral ruthenium 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 Ba is in Period 5, d-block
