Carbon : as an Element
Carbon is considered as the third most important element, after oxygen and hydrogen, for the existence of life on the earth. The name carbon is derived from the Latin word ‘Carbo’ which means ‘coal’. The earth crust contains only (0.02%) carbon which is present as minerals (like carbonates, hydrogen-carbonates, coal and petroleum) and the atmosphere has 0.03% of carbon dioxide. Fuels (like wood, kerosene, coal, LPG, CNG, petrol etc.), clothing material (like cotton, nylon, polyester), paper, rubber, plastics, leather, drugs and dyes are all made up of carbon. All the living things (plants and animals) are made up of carbon compounds.
