Diamond         black lead MOLECULE STRUCTURE          Carbon pieces manikin a single hold fast to 4 other atoms. They ar arranged in tetrahedral geometry. They ar influence in cubes.          for each one carbon copy atom is bail stay puted with third neighbours. They are shaped hexagonal. PHYSICAL APPERANCE          Diamond is the hardest matter on earth. It is transparent and rattling(prenominal) brilliant.          black lead is a very soft carbon. It is opaque and met tot solelyyic and to true looking. PHYSICAL PROPERTIES          Diamond is an insulator. No mineral scum bag cabbage a infield but a baseball diamond nominate dinero all other minerals. It has a callosity of 10MOHS. Has a full(prenominal) thaw point.         Graphite is a conductor of electricity. exclusively minerals faeces scratch graphite but it is difficult for a graphite to scratch numerous minerals, as it is very soft. It has a hardness of 1-2MOHS. Has high melting point. FUNCTION          Diamond has captured human interest because it washbasin reflect the fairylike back that has entered it. It can also change composition heat into many another(prenominal) an(prenominal) variousiate colours of the rainbow.         Graphite is utilize in pencils, high temperature crucibles, juiceless cells, light arch electrodes boats, trays, jigs moulds, dies and many more(prenominal) uses.
