Forbidden Gap The prohibited gap is defined as the space between the conduction and valence bands. This is a band that is not allowed to exist because it lacks energy. As a result, no electrons flow in this band. This gap will allow electrons to move from the valence to the conduction state.

It is otherwise known as a valence orbital, or a frontier orbital (i.e. an orbital at the "frontier" of chemical reactions, performing the interesting legwork to move … WebThe valence band is the band having the highest occupied energy. Conduction Band The valence electrons are so loosely attached to the nucleus that even at room temperature, few of the valence electrons leave the band to be free. These are called as free electrons as they tend to move towards the neighboring atoms.
