Covalent compounds are not crystal lattice structures. Ionic compounds are.


For solid ionic compounds, their crystal lattice is responsible for properties such as:

  • Not electrically conductive: there are no freely moving charged particles (i.e. e-, cations or anions) for the electric current to flow
  • Brittle: when a strong force is applied to the crystal lattice, part of the lattice is displaced. Like charges align and repel, and the crystal "cleaves" and shatters.
  • High melting point/boiling point, due to the strong ionic bonds and electrostatic forces of attraction and repulsion that hold ions in a lattice formation. Much energy is required to break apart these bonds.
