  • Giant Ionic structures
    • Examples of Ionic Structures
      • Sodium Chloride
        • High Melting point (801 °C)
        • Can't Conduct electricity when solid
        • Can conduct electricity when molten liquid
        • Can conduct electricity when Dissolved in water
      • Magnesium Oxide
        • Very high melting point (2850 °C)
        • Can't conduct electricity when solid
        • Can conduct electricity when molten liquid
        • Can conduct electricity when Dissolved in water
          • Not Very soluble though
    • What is an Ionic Bond?
      • Occurs between positive and negatively charged Ions
        • Metals and non-metals
      • The metals lose Electrons to have a stable structure
      • Non-metals gain electrons to have a stable structure
    • The structure
      • The have strong electrostatic forces
        • Because of the oppositely charged Ions
        • Lots of energy needed to break the bonds
          • Therefore have high melting and boiling points
        • Solids at room temperature
      • Cannot conduct electricity when solid
        • Electrons are in fixed positions, and can't move around
        • Can only vibrate in fixed positions
      • Can conduct electricity when molten liquid
        • Ions are free to move
          • Allows them to carry an electrical charge
      • Some are able to dissolve in the water
        • This is because the water molecules can split up the lattice
          • Can conduct electricity when dissolved in water
            • Allows them to carry an electrical charge
            • Ions are free to move
        • Has a structure of a Giant Lattice
