10Sodium chloride and magnesium oxide have:
- AHigh melting points
- BLow boiling points
- CStrong electrostatic attractions between ions
- Dweak intermolecular forces
11The melting point of MgO is higher than NaCl because magnesium ions are smaller so they can get closer to oxygen ions, making the bond stronger therefore more energy is needed to break the bonds.
