The quantum-statistic problem of atoms chemisorption with hydrogen-like electronic structure on semiconductor and dielectric crystalline surfaces is considered. The superficial states are described in tight-binding approximation. The self-consistent system of equations for calculating the charge and spin-polarized states of the adsorbed atom in Hartree-Fock approximation is derived.

Key words: adatom, chemisorption, surface, chemisorption energy
