An element X has a valency of 4 whereas another element Y has a valency of 1. What will be the formula of the compound formed between X and Y?

Academic Chemistry NCERT Class 9

Valency of element X = 4

Valency of element Y = 1

Elements : X Y

Valency : 4 1

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

Therefore, formula of the compound is XY₄.
