Metals conduct electricity well because their electrons can move more freely than those in nonmetals. The structure of a metal atom's electron cloud makes it easy for the atom to gain or lose electrons in chemical reactions. Electrons repel these loose electrons and sen...
The best conductor of heat is diamond with a thermal conductivity of more than 2,000 watts per meter per degree Kelvin at room temperature. Silver is the material with the second-highest thermal conductivity at 429 watts per meter per degree Kelvin. This makes silver th...
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.
Copper's outer electrons are detached easily, making it great at causing an electron chain reaction. Copper is also used because of its price. While its price is increasing, its still far cheaper than other conductors.
Examples of conductors include the human body, metals, aqueous solutions of salt, graphite, copper, silver and gold. Conductors are materials that can transfer heat and transmit electricity. Conductors have a high density, allowing particles to flow freely and collide.
Of the elemental metals, silver is the best conductor of heat. It has a thermal conductivity of 235, meaning that it is able to transmit that amount of heat energy a single foot per hour per degree Fahrenheit.
Silver is the most electrically and thermally conductive metal. Other metals with a high level of electrical conductivity are copper and gold.
