1. Symbol C An abundant nonmetallic element that occurs in many inorganic and in all organic compounds, exists freely in amorphous, graphite, and diamond forms and as a constituent of coal, limestone, and petroleum, and is capable of chemical self-bonding to form an enormous number of chemically, biologically, and commercially important molecules. Other significant allotropes include fullerenes and nanotubes.

See Periodic Table.
2. A carbon-containing gas, notably carbon dioxide, or a collection of such gases, especially when considered as a contributor to the greenhouse effect: plans for capturing and sequestering carbon produced by power plants.
a. A sheet of carbon paper.
