Question

In a compound with molecular formula X2Y3, the valencies of Y and X are

Answer 1

Answer:

X= +3 Y= -2

Explanation:

Answer 2

In a compound with molecular formula X2Y3, the valencies of Y and X are 2 and 3 respectively.

• There is a combination of X2 and Y3 in the given compound.
• This means they are in the neutral ionic form, which requires the exchange of cations and anions during forming.
• This exchange is done to create a balance between cations and anions.
• Loss of electrons by metals leads to cation and gain of electrons by non-metals leads to anions.
• In this compound, there is an exchange of their vacancies.
• Therefore, the valency of X is 3 and Y is 2.
