THE STRUCTURE OF SOLIDS

Diamonds are denser than graphite (3.5 vs. 2.2 g/cm3). Diamonds are higher melting, colorless when pure and non conductors of electricity. A third allotrope of carbon discovered in 1985 (yellow spherical carbon) has a molecular arrangement shaped like a geodesic dome (soccer ball), called ‘buckminister fullerene’ – ‘buckyballs’ for short. ................
