Which of the following species has the highest electron affinity?
Which of the following species has the highest electron affinity?
Show Hint
Electron affinity generally increases as you move across a period from left to right, but the trend can be influenced by electron-electron repulsion.
Updated On: Feb 10, 2026
- F-
- Cl-
- O-
- Na-
Show Solution
The Correct Option is C
Solution and Explanation
Oxygen's electron affinity surpasses that of \( F^- \) and \( Cl^- \) due to electron repulsion within the \( F^- \) ion, which reduces its stability. \( O^- \), being smaller and exhibiting less repulsion, possesses a greater electron affinity.
