Question

The valency of an element A is 4 and that of another element B is 2. The formula of the compound formed from A and B is $A_{2}B.$

• A. True
• B. False

Answer 1

The correct option is B False

Given:- Valency of element A is $4$

Valency of element B is $2$

$\therefore$ For forming a compound, an equal number of electrons transfer should take place.

For $4e^{-}$ transfer, two B required.

Formula of compound is $A{B}_2$.

Hence, it is a false statement.
