Suggest Corrections 0 Similar questions Q. Diamond does not have sea of electons. Why is plastic bad conductor? Diamonds are an exceptional thermal conductor and electrical insulators. Diamond is a bad conductor of electricity: Since each carbon atom is attached to the other four carbon atoms through strong covalent bonds. In case of diamond, each carbon atom is covalently bonded with four other carbon atoms and hence no free electrons are available to conduct electric current. As copper is an excellent conductor of heat, it is good for heat exchanger also. Here are 4 examples of bad conductors. On the other hand diamond is a good conductor of heat because the atoms present in diamond are strongly bonded or connected to each other due to which flow of heat energy acquired by one atom to another atom is possible and hence diamond is good . Is a good conductor of heat and electricity? Due to the tetrahedral arrangement of covalently bonded carbon atoms in diamonds, there are no free electrons that can move and carry currents in diamonds. The diamond is five times better at conducting heat than copper because it has a thermal conductivity of 22 W/ cmK. However graphite and diamond both are allotropes of carbon having the same composition but different structures. In a graphite molecule, one valence electron of each carbon atom remains free, Thus making graphite a good conductor of electricity. How are the atoms of Diamond and graphite bound together? Since the conduction of electricity requires the presence of free electrons, a diamond is a bad conductor of electricity.
