Web19. What trend in electron affinity do you see as you go across a period/row on the periodic table? What causes this trend? Electron affinity increases as you more left to right across a row. The nucleus charge increases so the atomic radius is smaller. Pull from positive nucleus is more important than repulsion from other electrons. WebTrends. IE increases across period from left to right. This is because since electrons are pulled closer to nucleus (see atomic radius), more difficult to remove them. IE decreases down a group from top to bottom. This is …

WebElectron affinity (the energy associated with forming an anion) is more favorable (exothermic) when electrons are placed into lower energy orbitals, closer to the nucleus. … WebIn the d-block, you have many competing factors such as then need to have a full s and p, to energetic nuances due to the d subshell being partially full, and all these affect the electronegativity. Thus, in the d-block you don't have a clear periodic trend for electronegativity as you do in the s and p blocks.
