Parts and their functions

• Diamond (हीरा) — Each carbon is bonded to four other carbon atoms in a rigid three-dimensional structure → hardest natural substance, very high melting point. Can also be made synthetically under high pressure and temperature.
• Graphite (ग्रेफ़ाइट) — Each carbon bonded to three others in a plane (hexagonal array, one bond is double); layers stacked one above the other → smooth, slippery and a very good conductor of electricity.
• Buckminsterfullerene (C-60) (बकमिंस्टरफुलेरीन (C-60)) — 60 carbon atoms arranged like a football. Named after the architect Buckminster Fuller (geodesic dome).
