How can you represent the composition of an ionic compound?
By the ratio of cations to anions in the empirical formulae.
Ionic compounds are non-molecular species, and their formulae are represented by their empirical formulae, simple, whole number ratios.
Of course, ionic species are electrically neutral (most matter is of course electrically neutral). So when the alkali metals form an ionic compound with the halogen species, because the alkali metals readily form a
For the following cations,
