An element X of valency 3 combines with another element Y of valency 2. What will be the formula of the compound formed?

Academic Chemistry NCERT Class 9

Valency of element X = 3

Valency of element Y = 2

Elements: X Y

Valency: 3 2

Formula for the compound formed between X and Y can be worked out by crossing the valency of the constituent elements.

Therefore, the formula of the compound is X₂Y₃.
