WebNov 20, 2024 · Electron affinity can be either positive or negative value. The greater the negative value, the more stable the anion is. Although affinity varies greatly across the periodic table, some patterns emerge. Generally, the elements on the right side of the periodic table will have large negative electron affinity. WebSince element B is on the left of A, its metallic character is higher than A. Part 2: Electron affinity:-It is the amount of energy released when an electron is added to the neutral atom in its gaseous state to form an anion.
