Magnesium oxide is an ionic solid with the same structure as sodium chloride.
Magnesium oxide has a very high lattice enthalpy of +3791 kJ mol-1.
(1) Describe the structure of magnesium oxide and include a diagram to show the arrangement of the particles.
(2) State the typical properties of solids with this type of structure.
(3) Describe the factors that affect lattice enthalpy.
(4) Suggest how this very high lattice enthalpy may affect the melting point of magnesium oxide.
