Which of the following has the highest electron affinity?
Options
(a) F⁻
(b) O⁻
(c) O
(d) Na
Correct Answer:
O
Explanation:
As the size of atom decreases, a larger amount of energy is released when an elctrn is added to an isolated gaseous atom. Among the given species, the size of O atom is smallest (Since, size of parent atom is smaller as compared to its anion), thus its elctrn affinity is highest.
