Forms Carbon Takes
Carbon is found free in nature in three allotropic forms: graphite, diamond, and fullerines. A fourth form, known as "white" carbon, is now thought to exist. Graphite is one of the softest known materials while diamond is one of the hardest. More recently, another form of carbon, buckminsterfullerene, C60, has been discovered.
