Higher electron affinity values for non-metallic atoms indicate a greater tendency to gain electrons. This tendency facilitates the formation of anions, which is a critical aspect of ionic bonding and the stability of ionic compounds.

Understanding Electron Affinity
Electron affinity refers to the amount of energy released when an electron is added to a neutral atom in the gas phase. This property is significant in understanding how non-metallic atoms interact during chemical bonding.
Importance of Electron Affinity
- Facilitates Anion Formation: Higher values of electron affinity indicate that the atom has a strong tendency to gain electrons, making it easier for the atom to form anions. Non-metals typically have high electron affinities because they are more electronegative and tend to attract electrons to achieve a stable electron configuration.
- Bond Formation: In chemical reactions, non-metals often gain electrons to form stable anions. This process is crucial for ionic and covalent bond formation, particularly in compounds where non-metals interact with metals or other non-metals.
Why Other Options are Incorrect
- Only Applies to Metals (a): This is false because electron affinity is a property that applies primarily to non-metals, which readily gain electrons.
- Irrelevant in Bond Formation (b): Electron affinity is very relevant; it directly influences how atoms bond and the stability of the resulting compounds.
- Always Low (c): This statement is incorrect as non-metals generally possess high electron affinities, reflecting their ability to easily gain electrons.
Conclusion
In summary, option 'D' is correct because higher electron affinity values indeed facilitate anion formation, highlighting the fundamental role this property plays in the chemistry of non-metals. Understanding electron affinity helps predict the behavior of non-metallic atoms in various chemical reactions.
