Carbon (atomic number 6, symbol C) is a chemical element, which is tetravalent and nonmetallic. It is among the few elements that have been known to people since antiquity. Carbon has several allotropes, among which are amorphous carbon, diamond, and graphite. Depending on the allotropic form, carbon's physical properties can vary widely. Graphite, for instance, is black and opaque, while diamond is very transparent. Graphite is so soft that it can produce a streak on paper while diamond is one of the hardest materials. Graphite has good conductor properties, and diamond has poor electrical conductivity. At the same time, it...Read More
