  • Covalent vs Ionic structures
    • Ionic structures
      • Giant lattice structure
      • Positive and negative ions attract
        • Strong electrostatic forces
          • Difficult to break down
            • High melting and boiling points
      • Can conduct electricity when liquid or dissolved.
        • Ions are free to move
          • Covalent compounds
            • Strong with weak intermolecular forces
              • Easy to break down
                • Low melting and boiling points
                  • Most are gases at room temperature
            • Cannot conduct electricity
    • Giant covalent structures
      • Hard but brittle
      • Extremely high melting points
      • Unreactive when solid
      • Doesn't dissolve in water
