Metals are commonly used in electronic devices and wires due to their high electrical conductivity, which allows them to efficiently transmit electric current. The structure of metallic atoms, characterized by a 'sea of electrons', enables free movement of electrons, facilitating electrical flow. This property reduces resistive losses that can occur in less conductive materials, ensuring that devices operate effectively and with minimal heat generation. Additionally, metals like copper and aluminum are not only good conductors but also possess desirable mechanical properties, making them suitable for various applications in electronics.
