WebCarbon, the elementary constituent of graphene and graphite, is the 6th element of the periodic table. Its atom is, therefore, built from 6 protons, Aneutrons, and 6 electrons, where A= 6 and 7 yield the stable isotopes 12C and13C, respectively, and A= 8 characterises the radioactive isotope 14C. WebGraphite is black and shiny but soft. The nano-forms, fullerenes and graphene, appear as black or dark brown, soot-like powders. Uses Carbon is unique among the elements in its ability to form strongly bonded chains, sealed off by hydrogen atoms.
