NettetIonization Energy and Electron Affinity--Similar Trend. Both ionization energy and electron affinity have similar trend in the periodic table. For example, just as ionization energy increases along the periods, electron affinity also increases. Likewise, electron affinity decreases from top to bottom due to the same factor, i.e., shielding effect. NettetThe electron affinity trend describes how as one follows the periodic table left to right electron affinity increases and how it usually decreases as one moves down a group of elements, top to bottom. While that’s a short description of the electron affinity trend, it would be helpful to dig deeper into the relationship between electron ...
