The following are true regarding ionic compounds;

  • In ionic compounds the ratio between cations and anions is given by the formula unit.
  • lonic compounds consist of cations and anions present in a constant ratio.

The term formula unit has to do with  the ratio of ions/atoms of a compound.

In molecules, neutral atoms are bonded to each other by covalent bonds and the formula of a molecule reflects the number of each atom in the compound. For instance, CH4 is composed of one neutral carbon atom and four neutral hydrogen atoms all linked by covalent bonds.

For an ionic compound, the formula unit shows the ratio of cations to anions in the compound.

Therefore, the term formula unit applies basically to ionic compounds   instead of the term molecule.
