TEXTO: HOW CAN GRAPHITE AND DIAMOND BE SO DIFFERENT IF THEY ARE BOTH COMPOSED OF PURE CARBON? By Miriam Rossi The distinct arrangement of atoms in diamond and carbon makes all the difference to their properties. In a diamond, each carbon atom is attached to four others, forming a rigid three-dimensional network. This accounts for diamond’s extraordinary strength, durability and other properties. Diamond, the hardest material known, can scratch all other materials. It conducts more than copper does, but it is also an electric insulator. The gemstone disperses light into a rainbow of colors, giving rise to the “fire” of diamonds. In comparison, the carbon atoms in graphite are arranged in layers. Graphite is soft and slippery and can be used as a lubricant or in pencils. The planar structure allows graphite to conduct electricity and heat as well as to absorb light so that it appears black in color. (Adapted from Scientific American, September 2002) The word fire in ‘the fire of diamonds’ can be best replaced by: *
a) flame.
