When the compound contains at least two polyatomic ions of the same formula.
Typically in writing an ionic compound, the cation is written first, then the anion.
Ionic compounds are conventionally represented by chemical formulas; but after contemporary knowledge ionic compounds have complex, long chain molecules.
BaI2 is ionic. Rest are covalent compounds.

The first step is to establish which elements are in the compound.
When writing a formula for an ionic compound, you must include it's charges on the various elements. For example: For the ionic compound Carbon Sulfide, Instead of it being written as "CS", It's written as "C2S4". 2 and 4 Being the numbers to even out the ion.
Binary ionic compounds are named by writing the name of the action, followed by the name of the anion. Potassium bromide is an example of an ionic compound.
it is a little bit of both?
MgCl2
An ionic compound is an example of a chemical compound.
