Energy Bands

Valence Band:The highest energy band,in a solid, that is completely filled or occupied by electrons at 0K is known as the valence band.
Conduction Band: The higher level of valence band that is partially occupied by electrons or vacant is known as the conduction band.

Energy gap is the gap between these two energy bands and an indication of several electrical or optical properties of solid.In semiconductor the forbidden gap or energy gap is 0.25eV-2.5eV
