Top Tips

  • Remember - where the bonding happens is different to the nature of the bonding (its definition)
  • Whenever giving a property of a substance, explain how that property links to its structure
  • Diamond: each C atom forms 4 strong covalent bonds in a giant covalent lattice
  • Graphite: each C atom forms 3 strong covalent bonds in a layered structure, with weak forces between the layers
