Answer:
False
Explanation:
In every substance, there is a valence band and there is a conduction band. The gap between the valence band and the conduction band determines Whether a substance is a conductor or an insulator.
Conductors have a narrow gap between the valence band and the conduction band while insulators have a large gap between conduction band and insulation band. However, elements with a large number of electrons in the valence band are non conductors.
