yes all materials conduct electicity , but some are good conductor , some poor and some very poor
Materials that do not conduct electricity are an insulator.
Insulator materials will not carry or conduct electricity.
Anything metallic can conduct electricity. Also molten ionic compounds and solutions of ionic compounds. Aqueous acids also conduct electricity.
Materials that do not conduct electricity well are Insulating materials, or insulators. Examples include glass, rubber, plastic, air, ceramic, porcelain, dry paper and dry wood. Pure water will not conduct electricity at all.
The conduct of electricity
Conductor are materials that conduct electricity. There are also semiconductors, which conduct electricity but not as well, and superconductors, which conduct electricity without resistance when very cold.
No, some materials (water, for example) conduct electricity and are incapable of becoming magnetic.
copper, metals...
Planets themselves probably do not conduct electricity, although it is likely that most planets do contain some conductive materials. The vast majority of the matter on the Earth does not conduct electricity very well, although large deposits of iron, silver, gold and copper all _DO_ conduct electricity.
Ammonia is a gas. Gases do conduct electricity, as all materials do. However, they conduct electricity so poorly that we consider them insulators. "Electricity" requires the movement of electrons. In a gas, these electrons are too dispersed to provided any measurable current.
I think it could be lead
It is not a metal. It tends to get shorter when heated.
