WebNov 3, 2024 · Electron affinity tends to increase (as in more energy is released when an electron is added to an atom) as you move up a group on the periodic table. Nobles gases have an electron affinity of approximately zero. There is a tendency for electron affinity to increase as you move left to right across a period. WebAn element's first ionization energy is the energy required to remove the outermost, or least bound, electron from a neutral atom of the element. On the periodic table, first ionization energy generally increases as you move left to right across a period.
