Which substance conducts electricity in both solid and molten states?

Similarly, you may ask, which substance will conduct electricity in both solid and liquid phases?

Since the ions cannot move, ionic solids are non-conductors of electricity. When the solid is melted to a liquid, however, the ions are free to migrate. Therefore, ionic liquids are good conductors of electric current. A conductor is a substance capable of transmitting electricity and/or heat.

Beside above, what substances can conduct electricity when solid? All solid metals have some conductive properties with gold and copper being among some of the best. Some basically non-metalic materials can also conduct electricity in solid form, such as graphite and silicon. Compounds of metals do not conduct electricity as a solid, but metals are good conductors of electricity.

Furthermore, why do metals conduct electricity in both solid and liquid states?

The electrons in a metal are mobile in both the solid and liquid states. In the salt, the ions are immobile in the solid crystalline form. Metals will conduct electricity in either solid or liquid state. Also, ionic compounds such as salt, which do not conduct electricity in their solid state will conduct when melted.

Can metals conduct electricity in molten state?

Molten metals do not always behave the same as their solid state. That said, electrically conductive metals still conduct electricity when molten but they become more resistant as the temperature rises.
