Which of the following materials is known for its ability to conduct electricity?

Metals are known for their excellent ability to conduct electricity due to their unique atomic structure. In metallic bonds, electrons are not tied to individual atoms but are instead free to move throughout the material. This "sea of electrons" allows metals to efficiently transfer electric charge, making them crucial in electrical applications and wiring. Common examples of conductive metals include copper, aluminum, and gold, all of which are widely used in electrical components because they provide low resistance to electric current.

In contrast, materials like wood, ceramic, and glass are generally considered insulators, meaning they do not conduct electricity well. Wood lacks the free-moving electrons necessary for conductivity, ceramics have tightly bound electrons in their structure, and glass is structured in a way that also restricts the movement of electrons, preventing it from conducting electricity effectively.
