Question

Please Explain band theory​

Answer 1

Answer:

In solid-state physics, the electronic band structure of a solid describes the range of energy levels that electrons may have within it, as well as the ranges of energy that they may not have.

Answer 2

$\huge\tt{{\color{blue}{AnS}}{\blue{wEr}}}$

Band theory, in solid-state physics, theoretical model describing the states of electrons, in solid materials, that can have values of energy only within certain specific ranges. ... The behaviour of an electron in a solid (and hence its energy) is related to the behaviour of all other particles around it.
