Giant Covalent Structures and Fullerenes

• Giant Covalent Structures:

  • High melting & boiling points
  • Don't contain charged particles (Don't conduct electricity)
  • Insoluble in water
• Nanotubes r fullerenes:

  • Tiny tubes of graphene

  • Delocalised electrons meaning they conduct electricity.

  • Strong covalent bonds mean a high tensile strength.

  • Low density, so can be used to strengthen materials without adding much weight
• Diamond:

  • Made up of a network of C atoms that each form 4 covalent bonds
  • Bonds take lots of energy to break, so it has a high melting point
  • Bonds hold the atoms in a rigid lattice structure, making diamond rlly hard (used to strengthen cutting tools)
  • Doesn't conduct electricity
