Elemental carbon exists in two well-defined allotropic crystalline forms: diamond and graphite. Carbon fibers, which are 5 to 10 μm thick fibers composed mostly of carbon atoms, demonstrate high stiffness, tensile strength, chemical resistance, temperature tolerance and low weight and thermal expansion. It is also used as a labeling tool in combination with a mass spectrometer for medical research. It is also stable to oxidation at this temperature. Graphite, another form of carbon, isn't as strong as diamond because the carbon atoms in graphite link together in rings, where each atom is only linked to one other atom. Diamond is also clear in appearance, unlike graphite, which is opaque. Carbon is a fascinating element. The ability of carbon atoms to form covalent bonds with other carbon atoms is the most unique of its bonding properties. Carbon is widely distributed in coal and in the compounds that make up petroleum, natural gas, and plant and animal tissue. As the name implies, Organic Chemistry is the chemistry of life. Carbon belongs to Group 14 of the periodic table. Their pioneering efforts earned them the Nobel Prize in 1996. The position of carbon midway in the periodic table makes it neither a metal nor a non-metal, making it equally likely to share electrons with either. Carbon is a smallest element of periodic table which has very special property which is not having any other. ( -SH ) helps stabilize proteins by forming disulfide bridges . These contribute to the diversity and complexity of carbon compounds existing on Earth. Chemically pure carbon can be prepared by termic decomposition of sugar (sucrose) in absence of air. The carbon cycle starts when living organisms convert carbon dioxide (14CO2 and 12CO2 from the atmosphere) into organic compounds by photosynthesis and release it back to the atmosphere by respiration. Special properties of carbon Carbon has a number of unique properties which influence how it behaves and how it bonds with other atoms:Carbon (see figure below) has four valence electrons which means that each carbon atom can form a maximum of four bonds with other atoms. Graphite exists as one of the giant covalent structures in nature. Isotopes of carbon are extensively used for radiocarbon dating (carbon-14), molecular structure and medical research (carbon-13). This enables carbon to form long, continuous chains, branches and loops consisting of carbon and hydrogen in hydrocarbons and only carbon in carbon allotropes such as C … Carbon isn't the only element that "prefers" 4 bonds. Over 10 million organic compounds consisting of some combination of carbon and other elements have been documented, with new organic compounds being conceived and synthesized every day. Graphene is simply one atomic layer of graphite arranged in a honeycomb lattice. However, the controlled synthesis of such nanomaterials has posed a great challenge to scientists.
