Web17 Apr 2014 · A valence electron is an electron that is outside a noble-gas core and can be used to form bonds to other atoms. Thus, the d electrons in transition metals are valence electrons. The energy of an (n − 1)d electron is close to that of an ns electron, so it can participate in bond formation.
