Carbon (from Latin carbo 'coal') is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—its atom making four electrons available to form covalent chemical bonds. It belongs to group 14 of the periodic table. Carbon makes up about 0.025 percent of Earth's crust. Three isotopes … See more The allotropes of carbon include graphite, one of the softest known substances, and diamond, the hardest naturally occurring substance. It bonds readily with other small atoms, including other carbon atoms, and is capable of … See more The English name carbon comes from the Latin carbo for coal and charcoal, whence also comes the French charbon, meaning charcoal. In See more Carbon is essential to all known living systems, and without it life as we know it could not exist (see alternative biochemistry). The major economic use of carbon other than food and wood is in the form of hydrocarbons, most notably the fossil fuel See more • Carbon chauvinism • Carbon detonation • Carbon footprint • Carbon star • Carbon planet See more Organic compounds Carbon can form very long chains of interconnecting carbon–carbon bonds, a property that is called See more Graphite Commercially viable natural deposits of graphite occur in many parts of the world, but the most important sources economically are in China, India, Brazil, and North Korea. Graphite deposits are of metamorphic origin, … See more Pure carbon has extremely low toxicity to humans and can be handled safely in the form of graphite or charcoal. It is resistant to dissolution or chemical attack, even in the acidic contents … See more WebThe most important organic chemistry concepts. In organic compounds, C-C single bond is always a sigma bond. In the C=C double bond, the first bond is always a sigma bond, while the second is a pi bond. If a carbon atom is bonded to 2 other C-atoms, it must then have 2 H-atoms to complete its valency of 4 and attain a stable octet electronic ...
