which element has the highest electrical conductivity (h) (Mg) (CL) (He)

Answers

aluminium Al 13 1.00

4. He

Conductivity is the measure of the ease at which an electric charge or heat can pass through a material.A conductor is a material which gives very little resistance to the flow of an electric current or thermal energy.Electrical conductivity tells us how well a material will allow electricity to travel through it.Usually metals are good conductors of electricity.

1. Chlorine is a non metal thus it will have the lowest electrical conductivity.

2. As a plasma, helium's electrons and protons are not bound together, resulting in very high electrical conductivity, even when the gas is only partially ionized.

3. Hydrogen is also electrically conductive above certain temperatures.

4. Since, magnesium is a metal thus it is also electrically conductive in nature but less than hydrogen and helium.

Therefore, Helium will have the highest electrical conductivity.
