Carbon (from Latin carbo 'coal') is a chemical element; it has symbol C and atomic number 6. ... The physical properties of carbon vary widely with the allotropic form.
The carbon group is a periodic table group consisting of carbon (C), silicon (Si), ... element that may have a few noble gas-like properties, though it is still most ...
Carbon (6 C) has 14 known isotopes, from 8 C to 20 C as well as 22 C, of which 12 C and 13 C are stable.The longest-lived radioisotope is 14 C, with a half-life of 5.70(3) × 10 3 years. . This is also the only carbon radioisotope found in nature, as trace quantities are formed cosmogenically by the reactio
Carbon nanotubes, also called buckytubes, are cylindrical carbon molecules with novel properties that make them potentially useful in a wide variety of applications (e.g., nano-electronics, optics, materials applications, etc.). They exhibit extraordinary strength, unique electrical properties, and are efficient conductors of heat.
Carbon fibers have several advantages: high stiffness, high tensile strength, high strength to weight ratio, high chemical resistance, high-temperature tolerance, and low thermal expansion. [2] These properties have made carbon fiber very popular in aerospace, civil engineering, military, motorsports, and other competition sports. [3]
Atomic carbon, systematically named carbon and λ 0-methane, is a colourless gaseous inorganic chemical with the chemical formula C (also written [C]). It is kinetically unstable at ambient temperature and pressure, being removed through autopolymerisation.
Carbon-14, C-14, 14 C or radiocarbon, is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.Its presence in organic matter is the basis of the radiocarbon dating method pioneered by Willard Libby and colleagues (1949) to date archaeological, geological and hydrogeological samples.
Carbon compounds are defined as chemical substances containing carbon. [ 1 ] [ 2 ] More compounds of carbon exist than any other chemical element except for hydrogen . Organic carbon compounds are far more numerous than inorganic carbon compounds.
