All gases are very poor thermal conductors
Helium is a poor conductor of thermal energy because it has low thermal conductivity due to its low atomic mass and weak interatomic forces. As a result, helium does not transfer heat as efficiently as other elements or compounds.
Gold is a much better conductor of heat than helium. This is because gold is a metal and has free-moving electrons that can easily transfer heat, whereas helium is a gas at room temperature with very low density and poor thermal conductivity.
With a thermal conductivity of 237 W/m.K aluminium is a good conductor of heat.
Copper is an example of a good thermal conductor due to its high thermal conductivity. This means it is able to transfer heat efficiently from one point to another. Copper is commonly used in electrical wiring and heat sinks for this reason.
Silver is the best metal which is the conductor of electricity and heat. Silver is the best electricity conducting element, but not the best heat conductor. Carbon(Diamond) and Helium(Helium II state) are even better conductors of heat.

helium is an insulator (poor conductor) of heat
The best conductor of electricity is Silver, while the best conductor heat is helium (in its Helium II state), but some people consider diamond as the best heat conductor.
It's not, there are materials that are better, like diamond.

Helium is not a good conductor of electricity since its valence band is full and there is a large gap between this and its conduction band which means that electrons cannot be readily promoted from the fermi level to the conduction band...hence electrons are not free to move and there is no conduction.

Yes, silver is just about the best conductor there is
Wood is a thermal insulator. It is a poor conductor of heat.
Not the best conductor of electricity. poor thermal conductor gain electrons easily hope this helps : )
