WebJan 23, 2024 · When moving to the right of a period, the number of electrons increases and the strength of shielding increases. As a result, it is easier for valence shell electrons to ionize, and thus the ionization energy decreases down a group. Why does ionization energy decrease down a group shielding? WebExample: Consider the alkali metals that belong to group 1: Li, Na, K, Rb, Cs and Fr. All these elements have the same number of valence electrons that is 1. Thus, the number of valence electrons moving down the group remains the same. Suggest Corrections.

WebFeb 23, 2016 · This results in a DECREASE in atomic radii across the Period, due to the increased nuclear charge which draws in the valence electrons. On the other hand, going down a Group, we go to another so-called shell of electrons, that build on the preceding shell. Atomic radii thus INCREASE down the Group. WebThe overall effective nuclear charge experienced by the valence electron in question is Z eff. You are right in thinking that the effective nuclear charge increases down as a group as the increasing nuclear charge has a greater effect on Z eff than the shielding effect of more inner electron shells.
