The ground-state properties like the nuclear densities and the root mean square radii of exotic mirror nuclei 8B and 8Li have been investigated using the Skyrme Hartree Fock and Symmetrized woods Saxon calculations Additionally, several nuclear observables have been investigated, including longitudinal elastic electron scattering form factors, binding energies, Coulomb displacement energies, magnetic dipole moments, and electric quadrupole moments. The results of the evaluation are contrasted with the experimental data that is currently available. It found that a common feature of the neutron and matter densities for the above-selected exotic nuclei is the long tail behavior. We assumed that both 8Li and 8B have a structure of the core nuclei 7Be and 7L plus a valence. It found that the structure of the valence one-neutron of 8Li and one-proton 8B is a pure 1p1/2 orbit. The elastic charge form factors of the above selected exotic nuclei are evaluated using the plane wave Born approximation and compared with those of their stable isotope 7Li and 10 B.
