Metals conduct electricity due to the presence of free-moving electrons, even though metals are neutral overall and contain no net charges. The outer electrons in metal atoms are loosely bound, forming what is known as the "electron sea." This electron sea allows electrons to move freely through the metal when a potential difference (voltage) is applied. As these free electrons carry charge, they enable the flow of electricity. Therefore, even in the absence of net charges inside the metal, the movement of these free electrons makes metals excellent conductors.
