Graphite - Wikipedia

2019-4-23 · Graphite is an electrical conductor, hence useful in such appliions as arc lamp electrodes. It can conduct electricity due to the vast electron delocalization within the carbon layers (a phenomenon called aromaticity). These valence electrons are free to move, so are able to conduct electricity.
