A theoretical quantum study on the distribution of electrophilic and nucleophilic active sites on silver surfaces with (100) orientation and modeled as finite clusters is reported. From Hartree-Fock and Density Functional Theory calculations with the LANL1MB and LANL2DZ basis set, we found that the electrophilic active sites are extended and they are formed by a group of atoms. The nucleophilic active sites were located on hollow positions. The numbers of electrophilic and nucleophilic active sites were 1.86X10¹⁴ and 5.98X10¹⁴ active sites cm^-2 respectively.
