Suchith K 7 years ago

In graphte each carbon is bonded with adjacent 3 carbons only. Since the valence electrons present in carbon are four,one electron is free. Since their is a free electron, it moves freely and conducts electricity. In diamond,each carbon atom is bonded with 4 carbons in a tetra-hedral structure,there are no free electrons to conduct electricity. Hence graphite is a good conducter of electricity but diamond is a insulater.

Because graphite has one free electron and diamond are tightly packed.
