Mostly, soot forms as a byproduct of combustive processes. In its less crystalline form, carbon is also known as soot. An amorphous form of carbon referred to as vegetal carbon is utilized predominantly for industrial purposes for the manufacture of bleaching agents and as a gas absorbent.
Graphite, an allotrope of carbon, is used as a lubricant, for pencil tips, as an electrode in dry cells, and as a component for high-temperature crucibles.

Equally important is the fact that carbon as a free element has numerous uses such as its application as a black fume pigment in inks for printers and rims for motor vehicles. Because of its electronic conductivity, it is used as an electrode in the industry. Under normal pressure and temperature conditions, graphite is the thermodynamically stable form of pure carbon. Diamond is the hardest natural substance and is also used as a cutting material besides its use as a gem. Pure carbon mostly exists in crystalline form and forms either graphite or diamonds as a modification. Additionally, the density for graphite is estimated to be 2.25 g/cm³ and that for diamond is approximately 3.51 g/cm³. Its half-life is 5730 years and it is used for the radiometric dating of organic substances. C14, on the other hand, is very rare and unstable. C13 is the more frequent isotope and is considered stable. However, there are 2 additional isotopes of carbon: C13 and C14. The physical and chemical properties of carbon are also dependent on the crystalline structure of the element.Ĭarbon has a relative atomic mass of 12 grams per mol. Chemically pure carbon may be prepared in the laboratory through the thermal decomposition of sucrose in the absence of oxygen. It has a melting point of 3550☌ and a boiling point of 4827☌. It has the atomic number 6 and is a non-metal. Within this group, it is the 1st element and, thus, is in the 2nd period. Carbon ( symbol C ) is a tetragen this means that it is in the 4th group of the periodic system of elements.
