It is becuse when metals have free electrons then metal lose electrons and form positive ions. Ions are responsible for electrical conductivity.

Conductors have free electrons in valence band. There is no forbidden energy gap between valence band and conduction band. Thus the electrons can readily jump from valence band to conduction band. Thus motion of electrons implies flow of current and hence metals are good conductors.
