The effective nuclear charge is the net positive charge experienced by an electron in a polyelectronic atom. The term "effective" is used because the shielding effect of negatively charged electrons prevents higher orbital electrons form experiencing the full nuclear charge of the nucleus due to the repelling effect of inner-layer electrons
