In this paper we consider a system of many adatoms adsorbed on a metallic surface. The surface electronic states, the binding energy and the change in work function due to charge transfer are calculated on the basis of CPA as functions of coverage. The partial density of states at different atomic sites are numerically computed for different values of coverage, intra atomic Coulomb repulsion parameter and atomic level of the ada tom.
