Highest electron affinity is shown by

Question

Highest electron affinity is shown by (A) O- (B) F- (C)  Cl2 (D) F2

Tardigrade Admin · Accepted Answer

Molecules of F 2, Cl 2 and anion F -, all have stable inert gas configuration. Thus, their electron affinity is almost zero. Hence, among the given, O -has the highest electron affinity.

Q. Highest electron affinity is shown by

$O^{-}$

$F^{-}$

$C l_{2}$

$F_{2}$

Molecules of $F_{2}, C l_{2}$ and anion $F^{-}$ , all have stable inert gas configuration. Thus, their electron affinity is almost zero. Hence, among the given, $O^{-}$ has the highest electron affinity.
