Which of the following metals is considered a good conductor of electricity?

Copper is known for its excellent electrical conductivity, making it a widely used material in electrical wiring and components. This is due to its atomic structure, which allows electrons to move freely, facilitating an efficient flow of electricity.

In addition to its conductivity, copper has desirable properties such as resistance to corrosion and high durability, further enhancing its suitability for electrical applications. While gold and aluminum also have good conductivity, copper's balance of performance and cost-effectiveness makes it a preferred choice in most electrical settings.

Iron, while it does conduct electricity, is much less effective than copper, making it less desirable for applications requiring high-level conductivity.
