The answer to this question would be: inner electrons
The effective nuclear charge is the net positive charge that applied to an electron of a polyelectronic atom. It was written with the formula of Zeff= Z-S where Zeff means the effective nuclear charge, Z is the nuclear charge and S is the average number of the electron between the electron and nucleus.
Since only inner electron is counted on S, the outer electron has no effect.
