Carbon has been known since ancient times. The origin of the name comes from the Latin word 'carbo' meaning 'charcoal'. Carbon has three forms: graphite, diamond and c60. Graphite form of carbon is a black, odourless, slippery solid and sublimes at 3825 �C. Diamond form is a clear or coloured; an extremely hard solid. C60 is Buckminsterfullerine. Carbon black burns readily with oxidants. Carbon is made by burning organic compounds with insufficient oxygen. There are close to ten million known carbon compounds, many thousands of which are vital to organic and life processes. Radiocarbon dating uses the carbon-14 isotope to date old objects.
