Which of the following statements are true about metals? (i) Valence band overlaps with conduction band. (ii) The gap between the valence band and the conduction band is negligible. (iii) The gap between the valence band and the conduction band cannot be determined. (iv) Valence band may remain partially filled.
The electrical conduction through metals is dependent on the type of valence band and its gap with the conduction band. This gap determines the conducting property of metal.
