  • Structure of Substances
    • IONIC
      • High melting and boiling point.
      • Only conduct electricity when molten or dissolved
      • Non-metal + Metal
      • Strong bonds
    • COVALENT
      • Strong bonds
        • Strong bonds but weak intermolecular forces
          • Simple Molecular
      • Will NOT conduct electricity
        • Exception is graphite since layers of ions can slide
      • GIANT
        • Lots of Strong bonds
        • High melting point
        • Example - Diamond, sand or Graphite
    • METALLIC
      • Strong bonds
      • Sea of delocalised electrons
      • Will ALWAYS conduct electricity
      • Delocalised electrons  in lattice structure
