I believe in a sample of sodium chloride (NaCl), the sodium and chloride ions are arranged into an orderly array of ions. Sodium Chloride is an ionic compound and consists of a giant lattice of ions. It has a higher melting point due to strong ionic bond between chloride ions and sodium ions. The structure conducts electricity in molten and aqueous form but does not conduct in solid form.
