Question

Which of the following nonmetals will form an ionic compound with Sc(3⁺) that has a 1:1 ration of cations to anions?

a) Na
b) F
c) O
d) N

Answer 1

The nonmetal that will form an ionic compound with (Sc ³⁺) in a 1:1 ratio of cations to anions is F (fluorine).

Step-by-step explanation:

The nonmetal that will form an ionic compound with (Sc ³⁺) in a 1:1 ratio of cations to anions is F (fluorine).

In an ionic compound, the cation (Sc³⁺) and anion combine to form a neutral compound. Since (Sc ³⁺) has a charge of +3, it needs three negatively charged ions to balance out its charge. Fluorine (F) has a charge of -1, so three fluorine ions (F⁻) would combine with one (Sc³⁺) ion to form the compound ScF₃.

Therefore, the correct answer is (b) F.
