= Effective nuclear charge
{wiki=Effective_nuclear_charge}
Effective nuclear charge (often represented as \\(Z_\{\\text\{eff\}\}\\)) refers to the net positive charge experienced by an electron in a multi-electron atom. While electrons are attracted to the positively charged nucleus, they also experience repulsion from other electrons. The effective nuclear charge accounts for both of these factors to give a more accurate measure of the attractive force an electron feels from the nucleus.
