The results of the calculations of binding of the orbitals of cations and anions with the solvent orbital using the model of eq. (1-5) give a set of graphs that fully or partially form two volcano-shaped dependencies (Figure ). The graphs show that the orbital energies for the anions are mostly lower than those for the cations. It means that the centers of the volcano-shaped dependencies on the energy scale are shifted to the left for the anions and to the right for the cations.
