Silver
Silver has the highest electrical conductivity among metals.
Silver exhibits the highest electrical conductivity among metals.
Silver is the best conductor of electricity among all metals. It has the highest electrical conductivity and thermal conductivity compared to other metals.
Argon gas has low electrical conductivity, as it is classified as a non-metal gas. However, it has good thermal conductivity, which means it efficiently transfers heat.
Thermal conductivity of uranium: 27 W/m.K. Electrical resistivity of uranium: 28.10-8 ohm.m.
The metal with the highest thermal conductivity is silver, followed by copper, then gold.
Silver has the highest electrical conductivity of all metals. It is highly conductive due to its free-moving electrons that allow electricity to flow easily through it.
The thermal conductivity of beryllium is 200 W/m.K.
The carbon allotrope we call diamond has the highest thermal (heat) conductivity of any material. It is far better an any metal (or anything else we know of) at allowing heat to pass through it. It is carbon (in its graphite allotrope) that has the highest electrical conductivity under normal conditions of any of the nonmetals. Any metal is a better electrical conductor, but carbon is good enough to make brushes for electrical motors out of. You'll recall that the brushes complete the electrical circuit between the wiring of the non-moving elements to the rotating commutator.
Silver is a shiny element that is a good conductor of both thermal energy and electric current. It has the highest electrical conductivity of any metal, making it highly effective for conducting electricity. Additionally, silver also has a high thermal conductivity, allowing it to efficiently transfer heat.
A solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity.
When we consider the two elements gold and lead, we find that gold has a (ball park) thermal conductivity of about ten times that of lead. If you guessed that gold is about ten times as good a conductor of electricity as lead (based on the information presented regarding thermal conductivity), you'd be on target. In general, thermal and electrical conductivity both "track" from metal to metal. Good electrical conductors are generally good thermal conductors.
