Answer:
For the compound A₃Y₂, the valency of Y is 3.
Explanation:
Valency of an atom is defined as the number of hydrogen atoms that can combine to an atom. It is also called combining capacity and is a whole number.
The valency of elements interchange during the formation of compound. The valency of one element becomes the subscript of the other element. We can say the the valency of anion will be the subscript of cation and the valency of cation will be the subscript of anion.
Here, we have the compound A₃Y₂.
Therefore, the valency of A is 2 and the valency of Y is 3.
