How did Antoine Discover carbon?
Carbon was first discovered as charcoal in prehistoric times. Antoine Lavoisier showed that diamonds are a form of carbon in 1772. He burned carefully weighed diamond and carbon samples and showed that both substances produced no water vapor and the same amount of carbon dioxide gas per gram.

Why is carbon named carbon?
The word carbon probably derives from the Latin carbo, meaning variously “coal,” “charcoal,” “ember.” The term diamond, a corruption of the Greek word adamas, “the invincible,” aptly describes the permanence of this crystallized form of carbon, just as graphite, the name for the other crystal form of carbon, derived …
What are allotropes of carbon?
When an element exists in more than one crystalline form, those forms are called allotropes; the two most common allotropes of carbon are diamond and graphite. Every carbon atom is covalently bonded at the four corners of the tetrahedron to four other carbon atoms.
