Quizplus · Accepted Answer

The elements N, S, and I are all non-metals and tend to gain electrons to form anions in binary ionic compounds. K, Ga, Pb, Ca, Fe, Hg, Li, and As are metals and tend to lose electrons to form cations in binary ionic compounds. Therefore, option D is the correct choice where all elements tend to form anions in binary ionic compounds.
