             Diamond Each carbon atom Hard Don't conduct electricity High melting and Boiling Point. >Strongly bonded to 4 other carbon atoms >In Giant 3D lattice structure Drills Cutting tools No charged Particles of free electrons

             Graphite Each Carbon atom Weak Forces of Attraction Used as: 3 of outer electrons in each carbon atom. The fourth electron >Strongly bonded to 3 other carbon atoms High Melting and Boiling Point Strong Covalent Bonds Giant Structure

        Silicon Dioxide (Sand) 3D structure like Diamond Silicon and oxygen atoms bonded together strongly. High Melting and Boiling Point NEVER conducts electricity.

>turning layers of hexagon Between layers So can slide over each other Pencil leads lubricant used to make the covalent bonds delocalised between layers. Delocalised Electrons Allows graphite to conduct electricity.
