O_h^7, T_d^2 and O_h^5 symmetry crystals were discussed to demonstrate universality of the empty-lattice approximation to obtain the topology and symmetry of the elementary energy bands creating the valence band of those crystals and to predict a localization of the maximum of valence electron density distribution in the unit cell. The elaborated concept of the elementary energy bands was applied to the (GaAs)_5/(AlAs)_5 superlattice and ordered solid solution Pb_{0.5}Sn_{0.5}S.
