Lavoisier noted the overall weight of the jar was unchanged and that when it burned, the diamond had combined with oxygen to form carbon dioxide.He concluded that diamond and charcoal were made of the same element – carbon.A large family of fullerenes exists, starting at C20 and reaching up to C540.The most recently discovered allotrope of carbon is graphene, which consists of a single layer of carbon atoms arranged in hexagons.Diamond’s high thermal conductivity is the origin of the slang term ‘ice.’ At typical room temperatures your body temperature is higher than the room’s – including any large diamonds you may just happen to have lying around.

Ancient cultures did not realize, of course, that these substances were different forms of the same element French scientist Antoine Lavoisier named carbon and he carried out a variety of experiments to reveal its nature.If these layers were stacked upon one other, graphite would be the result. Graphene’s discovery was announced in 2004 by Kostya Novoselov and Andre Geim, who used adhesive tape to detach a single layer of atoms from graphite to produce the new allotrope.Atoms of extraterrestrial noble gases helium-3 and argon-36 have been found trapped within buckyballs on Earth.In 1779, Swedish scientist Carl Scheele showed that graphite burned to form carbon dioxide and so must be another form of carbon.In 1796, English chemist Smithson Tennant established that diamond was pure carbon and not a compound of carbon; it burned to form only carbon dioxide.
