Carbon

(Science: chemistry, element) Sixth element (Z=6) in the periodic table, has 6 protons, often described as the basis of life on earth because of its chemical properties, has potential for use with silicon as a low-activation structural material for fusion reactors, in the form silicon carbide.

carbon tiles are often used in plasma-facing components because its low Z makes carbon a relatively nice impurity. It is also useful as a neutron moderator.

See: low-activation materials, plasma-facing components.

Abbreviation: c An abundant nonmetallic tetravalent element occurring in three allotropic forms: amorphous carbon and graphite and diamond; occurs in all organic compounds.An element that is characteristically in all organic compounds. With a valency of four, carbon can bond with four other atoms. Carbohydrates consists of carbon, hydrogen and oxygen atoms for example, where th.
