Other questions in this quiz

2. Why is graphite slippery?

  • The weak bonds between the layers are easily broken.
  • The bonds between each carbon atom break easily.
  • Each carbon atom is bonded to three others at 120· which make it easy to break the bonds.

3. Fullerenes...

  • are soluble in organic solvents
  • form brightly coloured solutions in inorganic solvents
  • can't conduct electricity
  • are not soluble in organic solvents

4. Nanoparticles are generally..

  • 50 nanometres across, where a nanometre is 10^-9
  • 150 nanometres across, where a nanometre is 10^-9
  • 100 nanometres across, where a nanometre is 10^-9 m
  • 100 nanometres across, where a nanometre is 10^-10

5. Why carbon atoms can form this type of structure?

  • They can form 4 strong bonds.
  • The electrons get excited when the bond and one of them moves to the 3s shell.
  • It only has 2 shells.
  • Its electrons are in the 2p shell.
