It does not react with sulfuric acid, hydrochloric acid, chlorine or any alkalis.

Graphite is a good electrical conductor while diamond has a low electrical conductivity.

It is present as a powder, and is the main constituent of substances such as charcoal, lampblack (soot) and activated carbon.

At normal pressures, carbon takes the form of graphite, in which each atom is bonded trigonally to three others in a plane composed of fused hexagonal rings, just like those in aromatic hydrocarbons.

Carbon's abundance, its unique diversity of organic compounds, and its unusual ability to form polymers at the temperatures commonly encountered on Earth enables this element to serve as a common element of all known life.

It is the second most abundant element in the human body by mass (about 18.5%) after oxygen.
