Electron affinity increases down the group

WebThe number of valence electrons increase as we move down groups in the periodic table, as electron affinity decreases. We can rationalize this by considering the shielding effect. This rule acknowledges that while nuclei attract … WebApr 8, 2024 · Across a period, the electron affinity increases as nuclear charge increases. Down the group, it decreases, as the nuclear charge decreases. Fluorine has the highest electronegativity and noble gasses are not included in this. The reason being they have a full valence shell and thus can neither gain nor lose electrons. 6. Shielding Effect
