In this research, we studied the quantum effect of the electronic density change effect of some sodium( Nan) clusters properties, electronic and spectral properties changes.We have been studied using density functional theory: (DFT/B3LYP(6-311+G(2d))). Density Functional Theory (DFT) is a computational method that derives properties of The sodium clusters (neutral and positively) based on a determination of the electron density of the clusters.
