Question

What is energy band?

Answer 1

In solid-state physics, the electronic band structure (or simply band structure) of a solid describes the range of energies that an electron within the solid may have (called energy bands, allowed bands, or simplybands) and ranges of energy that it may not have (called band gaps or forbidden bands).

Answer 2

energy band is the collection of individual energies of electrons surrounding an atom that is known as energy band
