Question

what are energy bands in solids???????​

Answer 1

Answer:

Suppose two isolated atoms are brought to very close proximity, then the electrons in the orbits of two atoms interact with each other. ... When isolated sodium atoms are brought together to form a solid, then the energy levels of the valence electrons spread into bands.

hope it helps u..!!!!

Answer 2

Answer:

Origin of energy bands formation in solids

Suppose two isolated atoms are brought to very close proximity, then the electrons in the orbits of two atoms interact with each other. ... When isolated sodium atoms are brought together to form a solid, then the energy levels of the valence electrons spread into bands.
