The aim of this work is the evaluation of the energy, repulsion energy 〈vee〉,attraction energy 〈ven〉, the potential energy 〈V〉,total energy 〈E〉,one-electron expectation value and inter –electron expectation value (where k is an integer takes the value -2,-1,1,2)for the ground state and for the different excited states (1s2 ns) and(n=3,4,5) of Li atom and Li-like ions such as Be+1,B +2 and C+3by using Hartree –Fock approximation in position space. A systematic study of the differences in electronic distributions between the singlet and triplet states are carried out . Finally all the studied properties are calculated using atomic units and using software MATHCAD 2001i.The aim of this work is the evaluation of the energy, repulsion energy 〈vee〉,attraction energy 〈ven〉, the potential energy 〈V〉,total energy 〈E〉,one-electron expectation value and inter –electron expectation value (where k is an integer takes the value -2,-1,1,2)for the ground state and for the different excited states (1s2 ns) and(n=3,4,5) of Li atom and Li-like ions such as Be+1,B +2 and C+3by using Hartree –Fock approximation in position space.
