Question

When monovalent cation (X) binds to divalent anion (Y) it will form

Answer 1

When a monovalent cation X binds to a divalent anion Y, a compound with the formula $X_2Y$ would be formed.

A monovalent cation is an atom that has lost an electron. Hence, such cation has a single positive charge. A monovalent cation X will, thus, be $X^+$

A divalent anion is an atom that has gained two electrons. Such anion has 2 negative charge. Thus, divalent Y would be $Y^2^-$

Since Y is a divalent anion, it requires 2 electrons in order to successfully bind with another charged atom, a cation to be specific. Thus, two of  $X^+$ would be required to successfully bind  $Y^2^-$

   $Y^2^-$ + $X^+$ + $X^+$ ----> $X_2Y$
