    • - the level of carbon in the atmosphere has been consistently rising
    • - fossil fuel consumption and carbon emissions continued to rise
  1. (carbon) an abundant nonmetallic tetravalent element occurring in three allotropic forms: amorphous carbon and graphite and diamond; occurs in all organic compounds
  2. carbon paper: a thin paper coated on one side with a dark waxy substance (often containing carbon); used to transfer characters from the original to an under sheet of paper
  3. (carbon) a copy made with carbon paper
  4. Carbon is the chemical element with symbol C and atomic number 6. As a member of group 14 on the periodic table, it is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. ...
  5. (Carbon (Apple)) Carbon is one of Apple Inc.'s procedural application programming interfaces (APIs) for the Macintosh operating system. It provides C programming language access to Macintosh system services. ...
  6. (Carbon (electronic sports team)) Carbon is a professional Major League Gaming (MLG) Halo 3 team. The team was formed at the MLG event in Orlando 2006 founded by Shockwav3, Karma, Strongside, and Gandhi. ...
  7. (Carbon (journal)) Carbon is a scientific journal published by Elsevier ScienceDirect. According to the journal's website, "Carbon publishes papers that deal with original research on carbonaceous solids with an emphasis on graphene-based materials. ...
  8. (Carbon) Element that provides the backbone for all organic polymers. Graphite is a more ordered form of carbon. Diamond is the densest crystalline form of carbon.
  9. (Carbon) An inclusion in a diamond that appears black to the unaided eye. Return to Top  »
  10. (Carbon) Main hardening element in steel. Usually, as carbon increases: tensile increases; ductility and weldability decline. Chemical symbol C.
  11. Carbon (C) occurs in nature as the sixth most abundant element in the universe and the 19th element in order of mass in the Earth's crust. Carbon reduces many metals from their oxides when heated with the latter, and small amounts of it greatly affect the properties of iron. ...
  12. (Carbon) Often used as shorthand for carbon dioxide (CO2) or carbon dioxide equivalent (CO2e).
  13. (carbon) A very common element in the universe. It is the basic chemical building block of life as we know it.
  14. (Carbon) the element that is one of the building blocks of all life.
  15. (Carbon) Chemical element, with the symbol C, an essential constituent of plant and animal organisms. Organic chemistry, also known as carbon chemistry, is based on it: more than a million carbon compounds are known. It is very common in nature, but not abundant. ...
  16. (Carbon) a non-metallic element that is the basis for all life
  17. (Carbon) Element of the periodic table with an atomic number of 6 and an atomic weight of 12.01
  18. (Carbon) An abundant, naturally occurring element. Often used in place of the word graphite. Graphite is an allotrope (form) of the element carbon. There are three allotropes of carbon, the other two being amorphous (having no definite form), and diamond.
  19. (CARBON) (Chemical Symbol C) - The most commonly used steel strengthening agent, carbon is present in practically all ferrous alloys and has tremendous effect on the properties of the resultant metal.
  20. (CARBON) Adds strength to stainless steel, but also lowers corrosion resistance. The more carbon there is, the more chromium must be added, because carbon offsets 17 times its own weight in chromium to form carbides, thus reducing the chromium available for resisting corrosion.
  21. (CARBON) As applied to forgings, the carbonaceous residue resulting from lubricant burned on the surface of the slug, cut from wrought material, or pressed part.
  22. (CARBON) For sharpness and edge retention.
  23. (CARBON) The basic building block of organic molecules needed for plant and animal life. During decomposition, carbon is released and then reused by plants and animals.
  24. (CARBON) The principal non-metallic element which when combined with iron in controlled amounts below 2.0% forms the materials known as carbon steels.
  25. (Carbon (C)) An atom and primary constituent of hydrocarbon fuels. Carbon is routinely left as a black deposit on engine parts, such as pistons, rings, and valves, by the combustion of fuel.
