Carbon Chemical & Physical Properties
By Anne Marie Helmenstine, Ph.D., About.com Guide
Diamond is one form of pure carbon.

Carbon

Atomic Number: 6

Symbol: C

Atomic Weight: 12.011

Discovery: Carbon exists free in nature and has been known since prehistoric time.

Electron Configuration: [He]2s22p2

Word Origin: Latin carbo, German Kohlenstoff, French carbone: coal or charcoal

Properties: Carbon is found free in nature in three allotropic forms: amorphous (lampblack, boneblack), graphite, and diamond. A fourth form, ‘white’ carbon, is thought to exist. Diamond is one of the hardest substances, with a high melting point and index of refraction.

Uses: Carbon forms numerous and varied compounds with limitless applications. Many thousands of carbon compounds are integral to life processes. Diamond is prized as a gemstone and is used for cutting, drilling, and as bearings. Graphite is used as a crucible for melting metals, in pencils, for rust protection, for lubrication, and as a moderator for slowing neutrons for atomic fission. Amorphous carbon is used for removing tastes and odors.

Element Classification: Non-Metal

Density (g/cc): 2.25 (graphite)

Melting Point (K): 3820

Boiling Point (K): 5100
