Question

Which one of the following amongs each pair will release maximum energy on gaining one electron (A = F, Cl), (B = S, Se), (C = Li, Na) 

(1) (A) = Cl, (B) = S, (C) = Li 

(2) (A) = S, (B) = Cl, (C) = Li 

(3) (A) = Li, (B) = Cl, (C) = S 

(4) (A) = Cl, (B) = Li, (C) = S 

Answer 1

The answer is (1) (A) = Cl, (B) = S, (C) = Li
