All metals can conduct heat and electric current, but some are more effective conductors than others. What are some factors that influence a metal's electrical conductivity? Metals are usually crystalline solids. In most cases, they have a relatively simple crystal structure distinguished by a close packing of atoms and a high degree of symmetry.

Insulators. Most solid materials are classified as insulators because they offer very large resistance to the flow of electric current.Metals are classified as conductors because their outer electrons are not tightly bound, but in most materials even the outermost electrons are so tightly bound that there is essentially zero electron flow through them with …
