Currently over twentymillion compounds have been reported in thechemical literature; about 90% of them areorganic, ie they contain carbon. The remainingcompounds are called inorganic and are formedfrom the other elements, of which there areabout 100. That carbon so dominatescompound formation is a result of the fact that itis almost unique in its ability to form longchains with other carbon atoms. [Carbon sneighbor in the periodic table, silicon, can dothis but rarely does.]
