We investigate the cross sections of the elastic electron or positron scattering from \(^{208}\)Pb, \(^{12}\)C, \(^{12,16}\)O and \(^{28, 32}\)S by the relativistic partial-wave expansion method using the static charge density distribution from the self-consistent relativistic mean field model and also calculate the charge form factor for \(^{12, 16}\)O and \(^{28, 32}\)S. The numerical results are compared with the available data. Calculations indicate that the extended charge density distributions of \(^{12}\)O and \(^{28}\)S have observable effects on the cross sections of the electron or positron scattering as well as the charge form factors.
