Why are metals good conductors of electricity?


Metals are good conductors of electricity because of the kind of bond that exists between their molecules. The molecules of metals are held together by a metallic bonding. As such, the atoms of metals are encased by a horde of electrons that are constantly in motion. This horde or “sea” of electrons is what makes metals good conductors of electricity.

Another reason is that metals have a high number of free atoms or valence electrons. These free valence electrons are channeled through a matrix formed by the bonds, instead of moving randomly within the metal. This organized movement causes electric conductivity.
