Whose electron affinity will be less than zero?

Question

Whose electron affinity will be less than zero? (A)  O2-  (B)  S2-  (C) both (a) and (b) (D)  O+

Tardigrade Admin · Accepted Answer

The electron affinity of O 2- and S 2- will be negative (i.e., less than zero) as energy is required to add an electron to them. (i.e., process is endothermic).

Q. Whose electron affinity will be less than zero?

$O^{2 -}$

$S^{2 -}$

both (a) and (b)

$O^{+}$

The electron affinity of $O^{2 -}$ and $S^{2 -}$ will be negative (i.e., less than zero) as energy is required to add an electron to them. (i.e., process is endothermic).
