Electron affinity increases down the group

WebMar 22, 2024 · So, down the group (from top to bottom), the atomic size increases. So Electronegativity decreases. And across the period (from left to right), the atomic size decreases, so the Electronegativity increases. For electronegativity values of elements, visit Interactive periodic table. 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.
