Calculation of the energy of subshells for six electron systems

Abstract

In the present study, the atomic properties have been calculated for each electron in (1s), (2s), and (2p) for the six-electron system for (Ne⁺⁴, Na⁺⁵, Mg⁺⁶, Al⁺⁷, Si⁺⁸, and P⁺⁹-ions) with an atomic number (Z=10 to 15). The calculated atomic properties include the one particle radial distribution function, the expectation values, the standard deviation  the inter-electronic distribution function f (r₁₂), the energy expectation value  and other properties. Hartree-Fock approximation has been used to determine each of these attributes. The software package Mathcad14 was used to acquire the results numerically. All results were derived using the atomic unit
