Vedclass · Answer

(A) The electron affinity $(EA)$ is defined as the energy released when an electron is added to a neutral gaseous atom or ion.Neutral oxygen $(O)$ has the highest tendency to accept an electron because it is not negatively charged.Anions like $O^-$ and $O^{2-}$ experience strong electrostatic repulsion from the incoming electron due to their negative charge,making the process endothermic or less favorable.Therefore,the neutral atom $O$ $(x=0)$ has the maximum electron affinity.

Which will have the maximum value of electron affinity among $O^x, O^y$ and $O^z$ ($x, y$ and $z$ are $0, -1$ and $-2$ respectively)?
