The electron configuration of an atom is the representation of the arrangement of electrons that are distributed among the orbital shells and sub-shells. If a transition metal ion is missing 2 or more electrons from the neutral state, one has to take these first two electrons from the 4s sub-shell because it is the outermost sub-shell of the atom . In the case of copper, a similar thing happens. It was founded in 1801 in the country of Mexico. Anomalous Electronic Configuration of Thorium.
