Eight allotropes of carbon: a) diamond, b) graphite, c) lonsdaleite, d) C 60 buckminsterfullerene, e) C 540, Fullerite f) C70, g) amorphous carbon, and h) single-walled carbon nanotube. Carbon is capable of forming many allotropes due to its valency.Well-known forms of carbon include diamond and graphite. In recent decades many more allotropes and forms of carbon have been discovered and researched including ball shapes such as buckminsterfullerene and sheets such as graphene.ight allotropes of carbon: a) diamond, b) graphite, c) lonsdaleite, d) C 60 buckminsterfullerene, e) C 540, Fullerite f) C70, g) amorphous carbon, and h) single-walled carbon nanotube.
