In this paper some atomic properties of He-like ions (Z=14 to 19) in the closed shells are investigated using implement Hartree-Fock wave function. This study started from the standard N-electron Hamiltonian in Hartree atomic units, ћ = ao = m = e =1. The atomic properties such as inter-particle distribution function, one-particle radial distribution function, two-particle radial density function, and all expectation values r< (<rn1 >, <rn12> ,〈V〉,〈T〉,〈E〉) are obtained numerically using programs Math CAD 2013. The non-relativistic Hartree-Fock energies for the ions (Si14+, P15+, Su16+, Cl17+, Ar18+, and K19+) were calculated. It was found that the correlation energies of the respective ions were -187.35802 Hartree, -215.73958 Hartree, -246.114 Hartree, -278.482 Hartree, -312.858 Hartree, and -349.231 Hartree, respectively.
