Carbon Different Forms. Unlike diamond it is an electrical conductor and a semi metal. There are a number of pure forms of this element including graphite diamond fullerenes and graphene.
D carbon is an orthorhombic sp 3 carbon allotrope 6 atoms per. It has been described as slightly harder than. The concentration of 12 c is further increased in biological materials because biochemical reactions discriminate against 13 c.
Carbon can be stored in a variety of reservoirs including plants and animals which is why they are considered carbon life forms.
Graphite is another allotrope of carbon. Diamond is probably the most well known carbon allotrope. Amorphous carbon refers to. Yet another form called amorphous carbon has no crystalline structure.
