carbon: - An element Atoms of carbon are the building blocks of living cells
carbon: What is Mac OS X?
carbon: sequestration generally refers to capturing carbon -- in a carbon sink, such as the oceans, or a terrestrial sink such as forests or soils -- so as to keep the carbon out of the atmosphere
carbon: Element number 6, both metal and non-metal Symbol C Crystaline forms are diamond and graphite Charcoal and coke are nearly pure carbon fuels Carbon molecules are the basis of all life The addition of carbon to iron makes steel Too much carbon makes steel into brittle cast iron See our Coal and Charcoal FAQ Density 2 25 g/cm3, 0813 lbs/cuin, diamond = 3 53 g/cm3, 1275 lbs/cuin, graphite = 2 51 g/cm3, 0907 lbs/cuin Los Alamos National Laboratory periodic table entry carbon

carbon: An abundant, naturally occurring element, one form of which is graphite
carbon: An elementary substance, not metallic in its nature, which is present in all organic compounds
carbon: Carbon content of particles in the water derived from living organisms (includes algae, waste products, dead or decayed organisms)
carbon: a copy made with carbon paper an abundant nonmetallic tetravalent element occurring in three allotropic forms: amorphous carbon and graphite and diamond; occurs in all organic compounds
carbon: The chemical element (symbol C) with an atomic number of 6
carbon: When united with oxygen it forms carbon dioxide, commonly called carbonic acid, or carbonic oxide, according to the proportions of the oxygen; when united with hydrogen, it forms various compounds called hydrocarbons
carbon: A nonmetallic element found in all organic substances and in some inorganic substances, as diamonds, coal, graphite, charcoal and lampblack
carbon: A substance used for filtration See activated carbon
carbon: The usual stable isotope is carbon-12; carbon-13, another stable isotope, makes up 1% of natural carbon. Carbon-14 is the most stable and best known of five radioactive isotopes (see radioactivity); its half-life of approximately 5,730 years makes it useful in carbon-14 dating and radiolabeling of research compounds. Carbon occurs in four known allotropes: diamond, graphite, carbon black (amorphous carbon including coal, coke, and charcoal), and hollow cage molecules called fullerenes. Carbon forms more compounds than all other elements combined; several million carbon compounds are known. Each carbon atom forms four bonds (four single bonds, two single and one double bond, two double bonds, or one single and one triple bond) with up to four other atoms. Multitudes of chain, branched, ring, and three-dimensional structures can occur. The study of these carbon compounds and their properties and reactions is organic chemistry (see organic compound). With hydrogen, oxygen, nitrogen, and a few other elements whose small amounts belie their important roles, carbon forms the compounds that make up all living things: proteins, carbohydrates, lipids, and nucleic acids. Biochemistry is the study of how those compounds are synthesized and broken down and how they associate with each other in living organisms. Organisms consume carbon and return it to the environment in the carbon cycle. Carbon dioxide, produced when carbon is burned and from biological processes, makes up about 0.03% of the air, and carbon occurs in Earth's crust as carbonate rocks and the hydrocarbons in coal, petroleum, and natural gas. The oceans contain large amounts of dissolved carbon dioxide and carbonates. carbon cycle carbon dioxide carbon monoxide carbon steel carbon 14 dating
