Some plastics can conduct electricity. Materials that insulate against electricity or do not conduct electricity are called dielectrics. While earlier plastics were dielectrics, scientists have developed plastics that can conduct electricity.

Glass is not a good conductor of electricity and is classified as an insulator not a conductor. An electrical insulator is any material that does not allow electrons and electric charge to flow freely. These materials make it hard for electric current to flow.

Iron is a conductor of electricity. Its electrical resistivity is 9.71 microohm centimeter. In comparison to copper, it is a poorer conductor of electricity. Nevertheless, generally, it is considered a good conductor of electricity.

In general, metals like copper and aluminum are the best conductors of electricity. Good conductors are able to allow electrons to easily flow through.

In general, metals make good conductors of electricity. These include copper, gold, silver and aluminum. Copper is a common conductor of electricity used in industrial applications because it is inexpensive to acquire, especially in comparison to gold and silver. Aluminium is not as efficient in con

Uranium and Radon, the densest solid and gas respectively, are the best conductors of heat. The ability to conduct heat is called specific heat and is closely linked to density. The denser a material is, the closer its specific heat is to zero and the more easily it conducts heat.

Many metals, like silver, copper, gold and aluminum, are good thermal conductors. Thermal conductors are materials that heat passes through easily. Conduction, or the transfer of heat, can take place within a single material or between two objects.

In general, metals make good electrical conductors while nonmetallic solids are good insulators, or materials that don't conduct electricity well. Electrolyte solutions, such as salt water, are also good conductors of electricity.

Gold is a very good conductor of electricity. It is often used as plating for connectors because it does not tarnish or corrode easily.

Metals conduct heat well for two reasons: metal ions pack very closely together in their molecular lattice, and electrons drifting through the metal carry kinetic energy around the lattice. The result is a quick elevation in particle motion that is expressed through heat energy. This conductivity is
