Some radial atomic properties have been obtained using two electron density function (r1,r2) in order to solve Hartree-Fock equations using slater type orbitals for Li-atom in different excited states (1s2 2P , 1s2 3S and 1S2 3P) using partitioning technique within the individual electronic shells of different configuration of Li-atom in position states. Radial expectations values for one electron and two electrons , correlation coefficients and and electron density at the nucleus have been calculated for these states of the same atom.
