Question

Define energy bands in solids

Answer 1

Insulator Energy Bands. Most solidsubstances are insulators, and in terms of the band theory of solids this implies that there is a large forbidden gap between the energies of the valence electrons and the energy at which the electrons can move freely through the material (the conductionband).
