These include decorating with pieces of diamond or black pigment in the rim of automobiles or ink of printer. The uses of carbon and its compounds are as follows:

#Reactivity of carbon free

It is a free element that comes with lots of uses. The carbon atom was discovered by Antoine Lavoisier. The energy of the carbon atom's first, second, and third ionisation is 1086.1 kJ.mol -1, 2351.9 kJ.mol -1, and 4618.8 kJ.mol -1, respectively. The electronic shell of the carbon atom is 2s 2 2p 2. The Ionic radius of the carbon atom is 0.015 nm (+4) 0.26 nm (-4). The melting and boiling point of carbon is 3652 ☌ and 4827 ☌, respectively. The density of the carbon atom is 2.2 g.cm -3 at 20☌. The atomic mass of carbon is 12.011 g.mol -1.

The chemical properties of carbon are as follows: The chemical element has the ability to bond with multiple elements.

It contains 6 protons in the nucleus and thus has the atomic number 6.Ĭarbon is both nonmetallic and tetravalent. This chemical element is represented with the symbol C. These include diamond and graphite with distinctive properties.Ĭarbon is highly unreactive under conditions that are normal. It has a number of allotropes and other forms of existence. Some characteristics of carbon are given below:Ĭarbon makes 4 electrons to form a covalent bond. Characteristics of carbon, chemical properties, applications, importance, and role of carbon are discussed below in detail. In this article, we will briefly discuss carbon. This makes the chemical formula appropriate – CO 2. However, from the technical perspective, carbon becomes carbon dioxide only if an atom joins two oxygen atoms. It is the primary greenhouse gas that is emitted by humans. In the study of climate change, carbon is often and generally termed carbon dioxide. You may have noticed, that carbon is the primary element in most compounds that are necessary to live. Without this, the existence of life could not have been made possible. The balance between increase of porosity and decrease in mechanical strength during activation is critical for developing new porous types of carbon materials in particular for carbon clothes and this can only be achieved by a careful control of the gasification reaction.Carbon is one of the most important elements of life. Proper control of gasification reactions is also of prime importance in manufacturing carbonaceous adsorbents like granular activated carbon clothes of high adsorption characteristics. Furthermore a great interest of aluminium producers 2 2 is 10 extending the lifetime of carbon electrodes in alumina electrolysis which primarily depends on reducing their consumption rates by air or carbon dioxide. Refractory applications of carbon in furnace linings, seals and vanes, as well as the use of carbon-carbon or carbon-ceramic composites in struc tures able to withstand corrosion at high temperature require a better understanding of the fundamentals involved in carbon-oxidizing gas (02' CO, H 0) reactions. Although these two objectives look somewhat contradictory, they are part of the general topics of understanding gasification reactivity of carbon. Basi cally there are two major issues in controlling the reactivity of carbon: i) reduction of the gasification rate of carbon materials in hostile environment ii) increase of the gasification rate in order to utilize carbonaceous compounds more effectively. During the last decade there has been a renewed interest in under standing from a fundamental point of view the gasification of carbon.
