Bonding, structure and the properties of matter (3 states of mater (solid,…

- - - - high melting points
      - high boiling points
      - large amounts of energy needed to break the many strong bonds
      - when melted of dissolved in water, can conduct electricity because ions are free to move so charge can flow
- - - - a single layer of graphite
      - has properties which make it useful in electronics and composites
      - the sheet is one atom thick
      - the network of covalent bonds makes it very strong - it is also incredibly light
      - contains delocalised electrons so can conduct electricity through the whole structure
    - - molecules of carbon atoms with hollow shapes
      - the structure is based on hexagonal rings of carbon atoms - but may also contain rings with 5 or 7 carbon atoms
      - first fullerenes discovered was the Buckminsterfullerene (C60) which has a spherical shape
    - - are cylindrical fullerenes with very high length to diameter ratios
      - there proportions make them useful for nanotechnology, electronics and materials
