Allotropes of carbon - Wikipedia

2019-4-20 · Graphite, named by Abraham Gottlob Werner in 1789, from the Greek γράφειν (graphein, "to draw/write", for its use in pencils) is one of the most common allotropes of carbon.Unlike diamond, graphite is an electrical conductor. Thus, it can be used in, for instance, electrical arc lamp electrodes. Likewise, under standard conditions, graphite is the most stable form of carbon.

Why does graphite conduct electricity - Why Center

These electrons are what enables electricity to flow through the metal. Because the structure of the metal and its free valence electrons has a lot to do with how well it conducts electricity, some metals are better than it than others. While nearly all metals and graphite can conduct electricity, some have a better atomical structure for doing so.
