ask more detail for carbon,,,""

=============================================

Carbon (IPA: /ˈkɑː(ɹ)bən/) is a chemical element that has the symbol C and atomic number 6. An abundant nonmetallic, tetravalent element, carbon has several allotropic forms.

The abundance of carbon in the universe, along with the unusual polymer-forming ability of carbon-based compounds at the common temperatures encountered on Earth, make this element the basis of the chemistry of all life as we know it.

Applications (1)

Carbon is a 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 not in living or formerly-living material (such as food and wood) is in the form of hydrocarbons, most notably the fossil fuel methane gas and crude oil (petroleum). Crude oil is used by the petrochemical industry to produce, amongst others, gasoline and kerosene, through a distillation process, in refineries. Crude oil forms the raw material for many synthetic substances, many of which are collectively called plastics.

Other uses

* The isotope carbon-14 was discovered on February 27, 1940 and is used in radiocarbon dating.
* Industrial diamonds are used in cutting, drilling, and polishing technologies.
* Graphite is combined with clays to form the 'lead' used in pencils. It is also used as a lubricant and a pigment.
* Diamond is used for decorative purposes, and also as drill bits and other applications making use of its hardness.
* Carbon (usually as coke) is used to reduce iron ore into iron.
* Carbon is added to iron to make steel.
* Carbon is used as a neutron moderator in nuclear reactors.
* Carbon fiber, which is mainly used for composite materials, as well as high-temperature gas filtration.
* Carbon black is used as a filler in rubber and plastic compounds.
* Graphite carbon in a powdered, caked form is used as charcoal for grilling, artwork and other uses.
* Activated charcoal is used in medicine (as powder or compounded in tablets or capsules) to absorb toxins, poisons, or gases from the digestive system.
* Carbon, due to its non-reactivity with many substances that corrode most materials, is often used as an electrode.

The chemical and structural properties of fullerenes, in the form of carbon nanotubes, has promising potential uses in the nascent field of nanotechnology.

Applications (2)

Carbon is an indipensable element in industry. By far, the greatest single use of carbon is in the form of coke for the iron and steel industry. The major portion of this coke is used in the reduction of iron ore in blast furnaces.

As in the rubber industry, the major applications for carbon blacks are in the printing ink, paint, paper and plastic industries. Minor amounts are used in the manufacture of dry cells and carbon brushes, and as insulation.

The largest single application for gas phase activated carbons is in the recovery of volatile organic solvents from air or vapor mixtures. Another large application is in the purification and separation of natural and industrial gases.

Main applications for pyrographite and the fiber forms of manufactured graphite are found as components for rockets, missile and other aerospace vehicles.
