Coal, soot, and diamonds are all nearly pure forms of carbon.Graphite is found in pencil "lead" and ball-bearing lubricants.Among the non-crystalline allotropes of carbon are coal, lampblack, charcoal, carbon black, and coke. Coke is nearly pure carbon formed when coal is heated in the absence of air.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.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).
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.
The smoke may have collected on the ceiling of their caves as soot.
Later, when lamps were invented, people used oil as a fuel.
It occurs in more different forms than any other element in the periodic table.
