Which property results from the crystal lattice structure of ionic compounds?

The properties of ionic compounds include forming crystal lattice structures, having high melting and boiling points, being hard and brittle and conducting electricity well when dissolved in water, but being insulators when in the solid form. The lattice energy is the energy of the bonds when in its crystal shape.

Explanation:

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
