Why Do Metals Conduct Electricity? | Materials Science & Engineering Student

Metals conduct electricity because they have “free electrons.” Unlike most other forms of matter, metallic bonding is unique because the electrons are not bound to a particular atom. This allows the delocalized electrons to flow in response to a potential difference.

Metals, Metalloids, and Nonmetals - Angelo State University

When metals coine with each other, the bonding is usually described as metallic bonding (you could''ve guessed that). In this model, each metal atom donates one or more of its valence electrons to make an electron sea that surrounds all of the atoms, holding the substance together by the attraction between the metal ions and the negatively charged electrons.
