The crystal lattice structure of covalent compounds is responsible for what set of characteristic properties?
Nov 20, 2016
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.
