Ionic Compounds

Sodium chloride, NaCl, forms when sodium and chlorine react together. It contains oppositely charged ions held together by strongelectrostatic forces of attraction – the ionic bonds. The ions form a regular lattice in which the ionic bonds act in all directions.

They have a high melting points as it requires lots of energy to break the strong ionic bonds.

They do not conduct electricity when solid as the ions are fixed in position.

But when dissolved or heated the bonds are broken, so the ions are free to move and they do conduct electricity.
