  • Why is graphite soft and diamond hard? Quora

    Dec 18, 2013· In diamond, each Carbon atom is bonded to 4 other Carbon atoms by sp3 bonds, which form a stiff 3-d network, which makes it a hard crystal.There are no delocalized electrons and is therefore and insulator. Graphite on the other hand has each Carbon atom bonded to 3 other Carbon atoms by sp2 bonds, which gives it a planar structure. Each Carbon gives one pair of delocalized electrons.8.
