Why do we use the term formula unit for ionic compounds instead of the term molecule?

Sagot :

Ionic compounds form crystal lattices, not molecules. The term formula unit is used to indicate the simplest whole-number ratio of ions in the compound.

For ionic substances, we use the phrase formula unit;

  • Cations and anions are ionic substances that are in constant proportion.
  • Continuously, Ionic compounds consist of cations and anions.
  1. An ionic compound molecule is connected using an electric attraction to another ionic compound molecule.
  2. The lattice structure produces this kind of attraction between molecules.
  3. The ionic compounds can be described as Formulas and not molecules as a result of this nicely ordered lattice structure.
