Galasso, Francis S. Structure and Properties of Inorganic Solids. This can be compared to how sports such as soccer, basketball, hockey, and football are played. The effect of the pull from these protons on the valence electrons determines the size of the atom, known as the atomic radius, and its ionization energy. Pauling, Linus. Therefore, the effective nuclear charge of Ar is, Zeff = 18 - 10 = 8+. It can be approximated by the equation: Z eff = Z S, where Z is the atomic number and S is the number of shielding electrons. Oxford: Oxford University Press, 2003. Electrons in s subshells are closest to the nucleus and therefore feel a stronger nuclear pull, creating larger Zeff values than their p subshells.
