Which of the following has the highest electron affinity?
1
2
3
4
Explanation:
and ions have stable electronic configuration, thus they will not accept further electrons, while needs electrons to achieve stable arrangement, thus it has highest electron affinity. Further, is a metal, thus it does not have any electron affinity.
