Question

What
are Valence bands conduction band? 12th std​

Answer 1

Valence Band:

The valence band is the outermost electron orbital of an atom of any specific material that electrons actually occupy.

Conduction Band:

A conduction band is a delocalised band of energy levels in a crystalline solid that is partially filled with electrons.

Also, the distance between the valence band and the conduction band is called the Band gap or Energy gap.

Answer 2

Answer:

The energy band formed due to the valence orbitals is called Valence band & that formed due to unoccupied orbital is called Conduction band.
