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.


The effective nuclear charge (ENC) of an atom is affected primarily by inner electrons.

The net positive charge imparted to an electron of a polyelectronic atom is known as the effective nuclear charge (ENC).

The formula is:

[tex]\rm Z_{eff} = Z-S[/tex],

Where [tex]Z_{eff}[/tex] = effective nuclear charge,

Z = nuclear charge, and

S = average number of electrons between the electron and the nucleus.

The outer electron has no influence on S since only the inner electron is counted.

Thus, Inner electrons would be responsible for primarily affecting the effective nuclear charge of an atom.
