A) \[{{O}^{2-}}\]
B) \[{{S}^{2-}}\]
C) both (a) and (b)
D) \[{{O}^{+}}\]
Correct Answer: C
Solution :
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).You need to login to perform this action.
