Carbon vs. Coal

Carbonnoun

(uncountable) The chemical element (symbol C) with an atomic number of 6.

Carbonnoun

(countable) An atom of this element, in reference to a molecule containing it.

Carbonnoun

A sheet of carbon paper.

Carbonnoun

A carbon copy.

Carbonnoun

A fossil fuel that is made of impure carbon such as coal or charcoal.

Carbonnoun

Carbon dioxide, in the context of global warming and climate change.

Carbonnoun

A carbon rod or pencil used in an arc lamp.

Carbonnoun

A plate or piece of carbon used as one of the elements of a voltaic battery.

Carbonverb

Carbonnoun

An elementary substance, not metallic in its nature, which is present in all organic compounds. Atomic weight 11.97. Symbol C. it is combustible, and forms the base of lampblack and charcoal, and enters largely into mineral coals. In its pure crystallized state it constitutes the diamond, the hardest of known substances, occuring in monometric crystals like the octahedron, etc. Another modification is graphite, or blacklead, and in this it is soft, and occurs in hexagonal prisms or tables. 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. Compare Diamond, and Graphite.

Carbonnoun

A carbon rod or pencil used in an arc lamp; also, a plate or piece of carbon used as one of the elements of a voltaic battery.

Carbonnoun

a sheet of carbon paper.

Carbonnoun

a carbon copy.

Carbonnoun

an abundant nonmetallic tetravalent element occurring in three allotropic forms: amorphous carbon and graphite and diamond; occurs in all organic compounds

Carbonnoun

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

Carbonnoun

a copy made with carbon paper

Carbonnoun

the chemical element of atomic number 6, a non-metal which has two main forms (diamond and graphite) and which also occurs in impure form in charcoal, soot, and coal.

Carbonnoun

carbon fibre

Carbonnoun

a rod of carbon in an arc lamp.

Carbonnoun

a piece of carbon paper or a carbon copy.

Carbonnoun

carbon dioxide or other gaseous carbon compounds released into the atmosphere, associated with climate change

Carbon

Carbon (from Latin: carbo ) is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds.

Coalnoun

A black, or brownish black, solid, combustible substance, dug from beds or veins in the earth to be used for fuel, and consisting, like charcoal, mainly of carbon, but more compact, and often affording, when heated, a large amount of volatile matter.

Coal

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen.
