What is Band?
In solid-state physics and chemistry, a band refers to a range of allowed energy states that electrons can occupy in a solid material, formed by the overlap of many atomic orbitals. The most important bands are the valence band (filled with bonding electrons) and the conduction band (where electrons move freely to conduct electricity). The gap between them is the band gap (E_g).
