The element x forms ions of charge +2 and the element y forms ions of charge -3. the most likely formula for a binary compound between these two elements is:

X3Y2

Explanation:

To represent the chemical formula of the binary compound, the valencies of both elements need to be exchanged.

Valency is the combining power of elements, ions or radicals. It is the value that shows how an element tend to combine with other elements.

In this particular question, the valence of the element X is +2, this means when it enters into chemical combination, it goes in with the power of positive 2. Same goes for the element Y, when it goes into chemical combination, it is expected that it goes in with the negative power of 3.

To completely write the chemical formula of the compound formed from the combination of both, we simply exchange the valency as said above. It must be noted that while the less electronegative element carry a positive or less negative charge , the more electronegative element will carry a negative or more negative charge.

We write the less electronegative element before the more electronegative element while writing the formula of the compound

is the formula.

Explanation:

Given:

Element X forms charge +2.Hence X is the cation and it's valency is 2.

Element Y forms charge -3.Hence Y is the anion and its valency is 3.

Method:

The number of cations = valency of anion

The number of anions = valency of cation.

Hence the correct formula will be .
