Question

magnesium reacts with another element to form a compound. which element most likely combined with the magnesium? a sodium b argon c sulfur d calcium

Explanation:

Magnesium (Mg) is a metal. Metals tend to react with non - metals to form ionic compounds. Sodium (Na) and Calcium (Ca) are metals, and Argon (Ar) is a noble gas (inert, rarely reacts). Sulfur (S) is a non - metal. So magnesium is most likely to combine with sulfur.

Answer:

C. Sulfur
