Carbon is an element that is everywhere around us, in millions of different chemical compounds, and it is an important part of both biofuels and fossil fuels. The carbon atoms bond easily with other atoms because they have four valence electrons, which leads to almost endless combination possibilities. In this film you will get to know more about the various forms of carbon; graphite, diamond, graphene, fullerene and amorphous carbon. We will also explain how nanotechnology can transform materials at an atomic level, to make them faster, stronger, lighter and more energy-efficient.
