Silver is the best metal conductor, but graphene is the best overall material at conducting electricity. Graphene consists of carbon atoms arranged in extremely thin sheets, and has the lowest electrical resistance of any commonly known material.

The conducting abilities of water depends on the type of water or the purity of it. Pure water, that does not have any other elements in it is a better insulator of electricity than it is a conductor. The opposite holds true for things like salt water, because of the extra elements in it.

Non-conductors of electricity are also known as insulators. Insulators do not allow a significant amount of electrical current to flow through. Some examples of insulators are glass, rubber and plastic.

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.

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.

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.

Silver is the most electrically and thermally conductive metal. Other metals with a high level of electrical conductivity are copper and gold.

Sodium is a soft, silver-white metallic element known for its electrical and thermal conductivity. At room temperature sodium is waxlike in composition and is malleable and ductile. Sodium must be derived through chemical means, as it is not found freely in nature.

Metals are good conductors of electricity because of their atomic structure that allows electric charges to pass through freely. The atomic structure of metals is unique because of the presence of one, two or three valence electrons in the outer orbit of the atoms, and this is true for all metallic

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