Which element is known to be the best conductor of heat?

Silver is known to be the best conductor of heat among all elements. This high thermal conductivity is due to its atomic structure, which allows for the free movement of electrons. In metals, when heat is applied, the electrons can quickly transfer energy from one atom to another, facilitating efficient heat conduction.

While copper and gold are also excellent conductors of heat, silver surpasses them in conductive efficiency. Silver's unique properties make it the go-to choice for applications requiring optimal thermal and electrical conductivity, such as in high-performance electronics and thermal interfaces. Aluminum, while a good conductor compared to many nonmetals, does not exhibit the same level of conductivity as silver, copper, or gold, making it less effective in this specific context.
