Study of atomic properties in K-Shell for Na9+, Mg10+, Al11+ ions in position space

In this paper the ground state  for  ions has been studied by using Hartree-Fock wave function,  the total energy, kinetic energy, potential energy,  radial expectation values  , We found the Hartree-Fock ground energy of Na 9 + = -114.231 hartree, of the Mg 10+ = -136.605 hartree and E h of the Al 11+ = -160.993hartree.  the total ground state energy gives results a good agreement with other results  published.
