Explain, in terms of structure and bonding, why magnesium oxide has a higher melting point than sodium chloride Magnesium and oxygen are more reactive elementsNaCl and MgO both have a giant ionic structure with strong electrostatic forces between oppositely charged ions. The Ions in MgO have a charge of 2 and -2, but in NaCl the charges are 1 and -1. So the bonds in MgO require more energy to breakMg²⁺ and O²⁻ ions are larger than sodium and chloride therefore the electrostatic forces between the ions are much stronger. This requires more energy to break.Sodium chloride is a simple molecular substance so there are only weak intermolecular forces which require little energy to breakQuestion 21 of 22 Loading... 22.
