Since the number of atoms in a macroscopic piece of solid is a very large number (N~1022) the number of orbitals is very large and thus they are very closely spaced in energy (of the order of 10â22 eV). The energy of adjacent levels is so close together that they can be considered as a continuum, an energy band.
