a stable, binary ionic compound exists where the cation (a) has a charge twice in magnitude than that of the anion (x). what would be the correct formula for this compound? a a₂x b a₂x₄ c a₄x₂ d ax₂

a stable, binary ionic compound exists where the cation (a) has a charge twice in magnitude than that of the anion (x). what would be the correct formula for this compound? a a₂x b a₂x₄ c a₄x₂ d ax₂

Answer

Explanation:

Step1: Understand charge - to - formula relationship

In a binary ionic compound, the overall charge must be zero. Let the charge on the anion (X) be (- 1), then the charge on the cation (A) is (+2) (since the cation (A) has a charge twice in magnitude than that of the anion (X)).

Step2: Determine the ratio of ions

To balance the charges and make the compound neutral, we need two anions (X) for every one cation (A). So the formula of the compound is (AX_{2}).

Answer:

D. (AX_{2})
