What Is Conductivity in Metals? - MetalTek
By: Dave Olsen. Conductivity in metal is a measure of a metal material's ability to transmit heat, or electricity (or sound). The reciprocal of conductivity is resistance, or the ability to reduce the flow of those. Understanding a material's tendency to conduct may be a critical factor in the selection of that material for a given application.

Electrical conductivity | physics | Britannica
Electrical conductivity involves a flow or current of free electrons through a solid body. Some materials, such as metals, are good conductors of electricity; these possess free or valence electrons that do not remain permanently associated with the atoms of a solid but instead form…. Read More.

Electrical Conductivity of Metals - ThoughtCo
Electrical conductivity in metals is a result of the movement of electrically charged particles. The atoms of metal elements are characterized by the presence of valence electrons, which are electrons in the outer shell of an atom that are free to move about. It is these "free electrons" that allow metals to conduct an electric current.
