When atoms start coming nearer to form a solid, there are different energy states(6N and 2N as per NCERT Physics pg 470). These different states which originally had the same energy spread out to form an energy band. Please explain why this happens. why does it spread out.

my question is its written in book that when we heat the crystle than an electron is free to move and it conduct electricity
mean when thermal enegy is provide to any crytal it conduct electricity
soo hot body conduct electricity very easyly the book say that the elctron may break away from a covalent bond and become free conductive electron
sun is too hot why it cannt conduct electricity
