Helium as a gas is an electrical insulator.
Yes, calcium is a good conductor of heat and electricity. Most metals are good conductors of heat and electricity. Most nonmetals are not good conductors of heat and electricity.
since iron is a metal and most metals are good conductors of electricity one can assume that iron is a fair conductor of electricity. The electrical conductivity of iron is approx. 1/6 from the electrical conductivity of silver (the best known conductor).
No. Helium is an inert gas, therefore, it is not conductive.
In its most commonly encountered from "white" phsphorus (where there are individual P4 molecules) is not a good conductor. This is also true for the red, and violet allotropic forms, which have a different structure. The black allotropic form has a metallic appearance but is still a poor conductor but is slightly better than the others, one reference describes it as a semiconductor at high temperatures.
Gold is a good conductor of electricity but a poor conductor of heat. This is due to its high electrical conductivity resulting from its high electron mobility. However, gold's ability to conduct heat is lower compared to other metals like copper or aluminum due to its high density and low specific heat capacity.
Helium is a poor conductor of heat and electricity because it is a noble gas with low density and lacks free electrons for conducting electricity.
helium is an insulator (poor conductor) of heat
Samarium is a good conductor for heat and electricity.
No, a good conductor of electricity is not a poor conductor of electricity. Good conductors like metals have high electrical conductivity, while poor conductors like wood or rubber have low electrical conductivity. The distinction lies in how easily they allow the flow of electric current.
helium is an insulator (poor conductor) of heat
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.
Zirconium is a good conductor of electricity, but it has poor thermal conductivity, meaning it is not a good conductor of heat.
Krypton is a poor conductor of either heat or electricity.
Fluorine is a poor conductor of electricity. It is a nonmetal and as such, it does not have the free-moving electrons that are necessary for conducting electricity efficiently.
Water is a poor conductor of electricity. However, the presence of ions in water make the solution a good conductor of electricity.
All metals conduct electricity to some extent. Chromium isn't an especially good conductor, but it does conduct.. so we can say that it is a poor conductor.
No. Copper is a good conductor of both electricity and heat.
