WebName: From the Latin carbo, coal. Atomic mass: 12.01. History: Known since ancient times. Occurrence: Carbon occurs naturally as crystalline graphite or diamond, or amorphously in charcoal, carbon black, coke, and white carbon. A new molecular allotrope, C 60, or buckminsterfullerene, was discovered in 1985. Appearance: Nonmetal solid. • Brillouin zone – Primitive cell in the reciprocal space lattice of crystals • Crystal engineering • Crystal growth – Major stage of a crystallization process • Crystallographic database
