WebIf there are eight electrons or if an atom completes its octet, it becomes stable. Noble gases have a stable electronic configuration as their octet is complete. They cannot accept more electrons. Electron affinity is the energy released when an isolated atom gains an electron. Since noble gases cannot accept electrons, their electron affinity ... Web15 jul. 2024 · To summarize the difference between the electron affinity of metals and nonmetals (Figure 1 ): Metals: Metals like to lose valence electrons to form cations to have a fully stable octet. They absorb energy (endothermic) to lose electrons. Why do nonmetals have a greater electron affinity than metals?
