Metals conduct electricity due to the presence of free-moving electrons within their structure. In metallic bonds, atoms share their outer electrons, creating a "sea of electrons" that move freely throughout the material. This mobility allows electric current to flow easily when a potential difference is applied. The free electrons can transfer energy, making metals excellent conductors of electricity. Additionally, metals like copper and aluminum are commonly used in electrical wiring because of their high conductivity. Understanding why does metals conduct electricity is crucial for various scientific and industrial applications.
