The symmetry effects on atoms in solids have been investigated extensively. Most of the earlier approaches assumed that the symmetry effects can be thought of as arising from point charges, distributed in the solid in a regular fashion. However, the point charge approach is basically incorrect, as one knows that electrons are not localized, but rather, that there is a finite probability of finding them anywhere in the solid. Also, electrons are indistinguishable from one another, which is implied in the statement of the famous Pauli Exclusion Principle. The present approach investigates symmetry effects on atoms in the solids, taking into account the fact that electrons are not localizable as points charges, and that they are indistinguishable. As a result of this approach, it was found that under certain circumstances, atoms may possess some additional energy levels which cannot be predicted by previous theories. This points to the experimental investigation of these effects and a confirmation of these would be encouraging for the present theoretical approach. These new energy levels predicted, if found experimentally, would increase greatly the number of materials which would laser, which could be a help in communication problems and others, as well.
