Which of the following metals is known to be the best conductor of electricity?

Silver is widely recognized as the best conductor of electricity among all metals. This exceptional conductivity is attributed to its atomic structure, which allows for the free movement of electrons. This characteristic makes silver particularly effective in applications that require efficient electrical conductance, such as in electrical contacts and high-performance circuits.

While copper also has excellent conductivity, it is slightly less effective than silver. However, due to its abundance, lower cost, and good conductivity, copper is more commonly used in electrical wiring. Gold, while a good conductor, is mainly valued for its resistance to corrosion and tarnish rather than its conductivity, and aluminum, although a decent conductor and often used in overhead power lines, does not match the conductivity levels of silver or copper.
