It is called effective because the shielding prevents the outer electrons from experiencing the full charge [1-4]. On the other hand, the effective nuclear charge is the net charge on the nucleus that attracts the valence electrons towards itself. Inorganic Substances: A Prelude to the Study of Descriptive Inorganic Chemistry. New York: Academic Press, Inc., 1983. new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0], However, {eq}K^+ {/eq} is a cation that has lost an electron giving it the electron configuration of Argon ({eq}[Ne] 3s^2 3p^6 {/eq}). An atom of chlorine is larger than sulfur because the addition of an electron increases the repulsions without an increase in attraction for the nucleus resulting in less screening. Having more energy levels within an atom means there are more core electrons that are held tightly to the nucleus. Page in the same ns, np group charge Z_ '' eff '' is the net positive experienced! Thus, Shielding constant, =(0.355)+(0.352)+(0.852) =4.15 = ( 0.35 5) + ( 0.35 2) + ( 0.85 2) = 4.15. effective nuclear chargeThat experienced by an electron in a multi-electron atom, typically less for electrons that are shielded by core electrons.
