Which metal is known to be a good conductor of electricity?

The correct choice, copper, is widely recognized as one of the most effective conductors of electricity. This is due to its atomic structure, which allows electrons to move freely and easily, leading to efficient electrical conduction. Copper’s high conductivity, durability, and relative cost-effectiveness make it a standard choice for electrical wiring and various electronic components.

While aluminum, gold, and silver are also good conductors, their properties differ; aluminum, although a decent conductor, has a higher resistance than copper and is generally used in applications where weight is a consideration. Gold is an excellent conductor and is highly resistant to corrosion, which makes it suitable for certain specialized electronic connections; however, its high cost limits its widespread use. Silver is the best conductor of electricity among all metals, but its expense and tendency to tarnish make it less practical for everyday applications compared to copper.
