Graphite (pencil lead) for instance is one of the softest forms of carbon, while diamonds are the hardest.Carbon compounds are named according to the number of carbons present in the basic chain, the presence of single, double or triple bonds, whether or not the carbon chain forms a cyclic structure and the elements or ions that substitute for hydrogens in the chain.Comprehensive data on the chemical element Carbon is provided on this page; including scores of properties, element names in many languages, most known nuclides of Carbon.
Fossile carbon production in 1996 was around 8,600,000,000 tons.
Approximate fossil fuel production per year: natural gas 2,000,000,000 tons; oil 3,300,000,000 tons; coal 2,300,000,000 tons.
Other uses include pencils, diamonds, steel, controls nuclear reactions, tire colorant, plastics, paint pigments, lubricants and much more.
Carbon has many allotropes each having very different physical properties from the other.
