Diamond and graphite are both allotropes of carbon. However only graphite can be used as an electrode explain why this is so even though they are both forms of carbon?

  • chemistry -

    Diamond is a tightly bound molecule of carbon atoms. Highly covalent bonds. Graphite, however, occurs in layers and electrons can be found in the areas between layers. These de-localized electrons are responsible for the electrical conductivity of graphite. Diamond is not a layered material.
    Here is a site about graphite.
