WebSulfur has several allotropes. There are also many carbon allotropes. Most people know of diamond, graphite, and charcoal, but fewer people know of the recent discovery of fullerenes, carbon nanotubes, and graphene. Descriptions of the physical properties of three nonmetals that are characteristic of molecular solids follow. Carbon WebDec 14, 2024 · Fullerenes. Until 1985 it was thought there were only two allotropes of carbon: diamond and graphite. But scientists thought they had detected the presence of another form of carbon in space. That mysterious new allotrope is C 60, or buckminsterfullerene. Other fullerenes exist too, like C 70, as well as ellipsoids and tubes. …
