CARBON ELEMENT FREE

Diamond is a second form of carbon but is much less common. This is also the thermodynamically most stable form. The most common form of pure carbon is О±-graphite.

Pure carbon is available in a number of different forms (allotropes).

This form of carbon is the subject of great interest in research laboratories today. More recently, another form of carbon, buckminsterfullerene, C 60, was discovered. Diamonds are also recovered from the ocean floor off the Cape of Good Hope. Natural diamonds are found in ancient volcanic 'pipes' such as found in South Africa. Carbon, as microscopic diamonds, is found in some meteorites. Graphite is one of the softest known materials while diamond is one of the hardest.

While silicon might take the place of carbon in forming a host of related compounds, it is not possible currently to form stable compounds with very long chains of silicon atoms.Д¬arbon is found free in nature in three allotropic forms: amorphous, graphite, and diamond. Organic chemistry, a 1/112th subset of inorganic chemistry, is the study of carbon and its compounds. Carbon is unique among the elements in the vast number of variety of compounds it can form. The atmosphere of Mars is very thin but what there is contains about 95 % CO 2.Д¬oal, petroleum, and natural gas are chiefly hydrocarbons. It is a component of rocks as carbonates of calcium (limestone), magnesium, and iron. Carbon is present as carbon dioxide in the atmosphere and dissolved in all natural waters. It is found in abundance in the sun, stars, comets, and atmospheres of most planets. Carbon is a Group 14 element and is distributed very widely in nature.
