Explain why the energy level of the atom becomes energy band in solids?

$\huge{\mathfrak{\purple{Answer}}}$

Each isolated atom has its own electrons in discrete energy levels. Atoms in a solid are so close together that the energy levels of each atom split into many energy levels so closely spaced that they become bands of energies.
