The proton and neutron densities, root-mean-square (rms) radii of proton density and neutron density, and neutron skin thickness of (4-10)He, (6-11)Li, and (7-12)Be isotopes are calculated using Skyrme-Hartree-Fock method with SLy4, SLy5, SLy6, and SLy7 force parameters. The evaluated results are compared with experimental data. Also, the results of halo nuclei ((6,8)He, (11)Li, and (11)Be) are compared with the results of other isotopes for selected nuclei having the same neutron configuration.
