Why Does Magnesium Oxide Have A High Melting Point?
Magnesium oxide (MgO) has a high melting point because of its strong ionic bonding and the arrangement of its ions in a crystal lattice structure. To understand this, you need to consider the nature of the chemical bonds in magnesium oxide. Ionic Bonding: Magnesium oxide is composed of magnesium ions (Mg²⁺) and oxide ions (O²⁻)….
