In this paper, was used the technique of fragmentation to analyze the systems studied based on the energy of repulsion between electronic pairs. The energy of Hartree - Fock was calculated for the carbon atom (C) and the similar ions (N +1 ) and (O +2 ), When the results of the energies compared with the global publications we found a large agreement also studied the atomic properties by using atomic units.

Estimation Hartree - Fock’s energy for the carbon atom and the ions are similar
