Solution

The correct option is D $M \to M^{+} + e^{-}$
Metallic character refers to the level of reactivity of a metal. Metals tend to lose electrons in chemical reactions, as indicated by their low ionization energies. So, An atom is said to be a metal if it loses one or more electrons when supplied with energy
