Chemistry

• Explain what a graphite is a good electrical conductor,soft and slippery


  -Bonds are covalent

  -Giant structure

  -These are delocalised electrons

  -can move through the structure-GOOD CONDUCTOR

  -layered structure

  -weak intermolecular forces between layers

  -no covalent bonds between the layers so that the layers can slide over each other-SOFT AND SLIPPERY
