What determines the ratio of ions in an ionic compound? answers on screenshot

In an ionic compound, the ratio of the ions has been based on the ratio of the charge. Thus option B is correct.

Ionic compounds are formed by the transfer of electrons between the anionic and cationic species. The formed compound has the transfer of a number of electrons, based on the charge.

Thus, with the ionic compounds, the ratio to the ions has been assigned based on the ratio to the charge of the ions.

B

Explanation:

For ionic compounds, the charge on the ions is the determinant of the ratio of ions in an ionic compound.

For instance, let us consider the ionic substance Al2O3, the charge on Al^3+ is +3 and the charge on O^2-is -2. This automatically implies that the ratio of ions in the compound is 3:2.

During exchange of valencies, the compound  is now written as Al2O3.
