Which substance has a chemical formula with the same ratio of metal ions to nonmetal ions as in potassium sulfide? (hint: first determine the chemical formula for potassium sulfide... then determine the ratio of metals to nonmetals. Finally, consider your answer choices. Take your time!)

• sodium oxide

• sodium chloride

• magnesium oxide

• magnesium chloride

Answer explanation

Notice... what group is potassium? What about sulfur? Compare the groups to the groups of the elements in the correct answer choice (sodium oxide)
