Pure water is a very bad conductor, but add a minute amount of impurities to it at the molecular level and it becomes a very good conductor. Pure water has a very high resistance to electrical conductivity Graphite is a good conductor of heat and electricity. 2) Graphite can conduct electricity because of the delocalised (free) electrons in its structure. 3) These arise because each carbon atom is only bonded to 3 other carbon atoms However, in diamond, all 4 outer electrons on each carbon atom are used in covalent bonding, so there are no. They then collide into neighboring electrons, thereby transferring their kinetic energy. The collisions emulate a domino effect and heat is propagated from the hot region, the region closer to the source, to the cold region, the far end of the metal. I say pure metal because alloys are relatively poor conductors of heat and electricity

Electricity is a steady flow of electrons or electrically charged particles through a substance.
