Giant covalent structures — practice question

Graphite is a form of carbon. What property allows graphite to be used as a lubricant?

  • AGraphite contains unbonded electrons which move through the structure.
  • BGraphite contains weak covalent bonds so the atoms move easily.
  • CGraphite has a low melting point so it easily turns into a liquid.
  • DGraphite has weak attractive forces between layers so they can move.
