C3 - Structure

• Diamond

  • Four strong covalent bonds for each carbon atom
  • Very hard ( Strong Bonds )
  • Very high melting/boiling points
  • Doesn't conduct electricity
• Graphite

  • 3 covalent bonds for each carbon atom
  • layers of hexagonal rings
  • high melting point
  • Layers free to slide due to weak intermolecular forces between layers
  • Soft - can be used as a lubricant
  • conduct electricity and heat due to one delocalised electron per carbon atom
• Fullerenes

  • hollow shaped molecules
  • based on hexagonal rings
  • C60 hqs a spherical shape, simple molecular structure (Buckministerfullerene
• Nanotubes

  cylindrical fulgerele with high length to diameter ratio
• Graphene

  a single layer of graphite
• Uses of Nanoparticles

  • Medicine
  • Electronics
  • Sun Creams - better skin coverage and more effective protection against cell damage
• How do nanoparticles have properties different from those for the same materials in bulk?

  Higher surface area to volume ratio
