Solid state diamond is non conducting but graphite is conducting

1.	Solid state diamond is non conducting but graphite is conducting
Answer» DIAMOND is non-conducting but graphite is conducting. This is because in diamond, ONE C-atom is bonded to 4 other carbon atoms in a tetrehedral manner and there are no free electrons to allow FLOW of ELECTRICITY. On the other hand, in graphite, one C-atom is bonded to 3 other C-atoms and there is one free electron for each C-atom. This electron is free to move and thus, allows the flow of electricity. HENCE, graphite can conduct electricity unlike diamond
