Question

Element $X$ is a metal with a valency 2. Element $Y$ is a non-metal with a valency 3.

Solution

The correct option is B $X - 2 e^{-} \to X^{2 +}$
Element $X$ is a metal with valency 2 that means it is a reducing agent and can release 2 electrons but cannot accept while $Y$ is a non-metal with a valency 3 that means it can accept 3 electrons and the stable ion is $Y^{3 -}$ .

So the balance equation for formation of ion is :

$X - 2 e^{-} \to X^{2 +}$

Option (B) is showing addition of two electrons that will not be able to form stable ion $Y^{3 -}$ . Metal ion $X^{+}$ is also unstable.
