The formula for an ionic crystal is determined by the ratio of cations to anions that balances the charges to create a neutral compound. It is represented as the simplest whole number ratio of the ions in the crystal lattice, such as NaCl for sodium chloride.
The term for the simplest ratio of ions in an ionic crystal is the formula unit. It represents the ratio of positive to negative ions in the crystal lattice that balances the overall charge. This formula unit is the smallest unit that shows the ratio of ions in an ionic compound.
Actually, a single unit of an ionic compound is referred to as a formula unit. Unlike molecules, ionic compounds do not exist as discrete molecules but as an arrangement of ions in a crystal lattice.
When you pound an ionic crystal with a hammer, the strong electrostatic forces holding the ions together are disrupted, causing the crystal to shatter.
The ionic formula for cyanate is CNO3-
MgCI2 does not exist. The formula is MgCl2 with a lowercase L. This compound is ionic.

MgO is an ionic compound and all the ionic compounds are represented by their emperical formula because actual no of atoms can not be represented due to a very huge crystal formation.(crystal lattice).
ionic crystal
A molecule if it is a compound, an atom if it is an element and a formula unit if it is an ionic crystal.
We use the term formula mass for ionic compounds because they do not exist as discrete molecules like covalent compounds. Instead, ionic compounds exist as a three-dimensional array of ions arranged in a crystal lattice. Therefore, the term formula mass better reflects the overall mass of the compound, considering all the atoms and ions present in its formula unit.

When positive ions and negative ions are nearby they are attracted and pair up building an Ionic Crystal.
MgCI2 does not exist. The formula is MgCl2 with a lowercase L. This compound is ionic.
Ionic compounds tend to form a crystal lattice structure.
The ionic formula for boron iodide is B2I6.
