Carbon also occurs in a form, discovered only recently, known as fullerenes or buckyballs.
Buckyball carbon holds the promise for opening a whole new field of chemistry (see accompanying sidebar).
Carbon occurs extensively in all living organisms as proteins, fats, carbohydrates (sugars and starches), and nucleic acids.
Humans have been aware of carbon since the earliest of times. The black color of smoke is caused by unburned specks of carbon.
Carbon allotropes that lack crystalline structure are amorphous, or without crystalline shape.
The allotropes of carbon have very different chemical and physical properties. Graphite does not melt when heated, but sublimes at about 3,650°C (6.600°F).
Founded in 2002 by Nobel Laureate Carl Wieman, the Ph ET Interactive Simulations project at the University of Colorado Boulder creates free interactive math and science simulations.
Coal, soot, and diamonds are all nearly pure forms of carbon.In 1787, four French chemists wrote a book outlining a method for naming chemical substances.The name they used, carbone, is based on the earlier Latin term for charcoal, charbon. Allotropes are forms of an element with different physical and chemical properties.Watch a sample video | Learn more | Table of contents | About the author Thinkwell's Chemistry is a two-semester college-level course that's accessible enough for introductory college chemistry courses, but rigorous enough for science majors.It's taught by top professors from prestigious universities, so you'll have help from our nation's best chemistry teachers whenever you need it.
