Carbon is an element that takes the solid form of either graphite or diamond. Carbon is one of the basic elements of any living thing.
Carbon is known as the most essential element for life, and it's the second most abundant — after oxygen — in the human body. Carbon paper was an early method of making copies, using a sheet of paper coated with wax and, originally, carbon soot. The copy that results from writing or typing on paper that's placed on top, with a blank page beneath the carbon paper, is called a carbon copy. The Latin root of carbon is carbonem, “charcoal.”
