Element X reacts with element Y to give a product containing X3 + ions and Y2 - ions.

What is the formula of the product?

Express your answer as a chemical formula.

X₂Y₃

Explanation:

X⇒X³⁺ + 3e⁻ / *2

Y + 2e⁻ ⇒ Y²⁻ / *3

2X⇒2X³⁺ 6e⁻

3Y + 6e⁻⇒ 3Y²⁻

2X + 3Y ⇒2X³⁺ + 3Y²⁻ ⇒ X₂Y₃

Electron from one side and from other side can be shortened so we multiply half equations to get equivalent number of electrons on both side. Next step is summing these two half equations. Element Y takes two electrons from element X, so X become positive charged, and Y become negatively charged. It is very likely that element Y have greater electronegativity.
