Periodic trend of electron affinity
Did you know?
WebThe electron affinity (EA) is the energy change for the process of adding an electron to a gaseous atom to form an anion (negative ion). X ( g) + e − X − ( g) EA 1. This process can be either endothermic or exothermic, depending on the element. The EA of some of the elements is given in Figure 6.35. WebMar 23, 2024 · Periodic table with electron affinity values is shown above. The values of electron affinity are given in kJ/mol. Values in parentheses ( ) are predicted values. Electron affinity is the amount of energy change (ΔE) that occurs when an electron is added in the outermost shell of an isolated gaseous atom.
