- C2:Giant structures
- Graphine
- Made from Carbon
- Black
- Soft
- Slippery
- Lubricant (in pencil leads)
- Conducts electricity
- Free electrons (so can move)
- layers can slide over each other
- weak forces between its molecules
- Explain why Graphene is strong; ( 3 marks)
- Graphene is strong because it has strong covalent bonds. it also has a lattice structure.
- Explain why Graphene can conduct electricity (2 marks)
- Graphene has free electrons so therefore it ca conduct electricity
- Explain why Graphite is a lubricant (2 marks)
- Graphite is a lubricant because it is slippery and its layers can slide over each other. it has weak forces between its molecules.
- Diamond
- Hard
- Made from Carbon
- 4 strong covalent bonds
- Clear
- High melting point
- Do not conduct electricity
- Very hard
- All the atoms are joined in diamonds.
- Each atom in a diamond is bonded to 4 other atoms
- Graphine
