The nuclear structure of the ground state for even 12,14,18 N isotopes are studied within the shell model framework through the longitudinal elastic electron scattering. The generate wave functions from two-body interaction of Cohen and Kurath in the p-shell for 12,14 N, and psdsu3 interaction for 18 N nucleus. The exact value of the center of mass correction in the translation invariant shell model (TISM) are re-examined for longitudinal form factors. The contribution of a higher 2p-shell configuration resolves some discrepancies with the experiments for the form factors at q-values. The inclusion of the core polarization effects through an effective nucleon charge gives a reasonable agreement for the present results with available data. The occupancy percentage with respect to the valance nucleons is also calculated.
