Graphite

• • consists of flat layer carbon

  
• • each carbon atom is bonded to 3 other atoms using its 3 outer electrons
• • one electron from each carbon atom is delocalised along the layers of carbon atoms
  • these delocalised electrons allow graphite to conduct electricity
• • the forces between layers are very weak and they are able to slide past each other
  • makes graphite soft and useful as lubricant
• • graphite has very high melting and boiling point
  • a lot of energy is needed to break strong covalent bonds
