In this research we studied some atomic properties of the like ions of the He-atom in the closed shells by using Hartree-Fock(HF)wave function,In this research we calculated(i)non-relativistic energy (Hartree-Fock energy E) for the(, O 6+ ,and F 7+ and we found the correlation energy of the-44.73664 Hartree , O 6+-ion-59.11233 Hartree and for the F 7+-ion-75.486 Hartree) and we compared these results with some experimental results. we found large agreement .(ii)Nuclear Magnetic Shielding

... t was found ((dia for N 5+ =1.187X10-4 ,O 6+ =1.365X10-4 and for F 7+ = 1.542X10-4),and (iii) we examined the influence of the atomic number on some atomic properties where Z=7 for Z=8 for O 6+-ion and Z=9 for F 7+ .
