Carbon is an important chemical element represented by symbol C. Carbon has a large number of organic compounds because it can create strong bonds with other elements and itself. Calcium carbonate (limestone) is magnesium and iron components of carbon.
There are three allotropes of carbon in the nature. Amorphous, graphite and diamond. Graphite is the most common soft materials and diamond is one of the hardest.
All physical and chemical properties of the carbon element is related to the crystal structure. High temperatures required for melting and evaporation, allows breaking the covalent bond of the three-dimensional crystals. Elemental carbon in the two crystalline structures is found in diamond and graphite.
Chemically pure carbon, sugar (sucrose) is obtained by decomposition by heating under vacuum. Other substances in the carbon is removed by improving the flame of chlorine gas. Then wahed with water and separated from the chlorine and hydrogen gas environment. Elemental carbon is a very heavy material. It is nonsoluable in water, diluted acid and alkali and organic solvents. It combines with oxygen at high temperatures and generates carbon monoxide. It only reactions with fluorine from halogens.
