plastic, steel, zinc, and carbon
it can be demonstrated by electrolysis with copper anode and graphite Cu-2e=Cu_2+
If it is made of metal, it is a conductor.
A metal key would conduct electricity.
It depends on the liquid. Oil would not be a good conductor of electricity. Water is a good conductor, though distilled water is not. Any liquid metal or ionic compound would be a good conductor.
Something that conducts electricity with little resistance. one really good conductor is metal.
A plastic spatula is not a conductor, as electricity does not transfer through plastic. A metal spatula is a conductor, since the metal used in kitchenware is often steel (stainless is the most popular), and steel is a conductor. While a better conductor would be copper, aluminum, silver, or gold, steel does conduct electricity.
it would be a conductor, as most metal conducts electricity.
It matters what kind of wire like a cell phone charger would not be a conductor but a wire made for braces would be a big conductor. Also anything metal is a positive conductor of electricity. :)
Silver is part of the metal group on the Periodic table of elements and metals are good conductors of heat and electricity so silver would be a good conductor and insulator.
I believe chlorine would be a bad conductor of electricity. Not sure about the heat. Usually one would want to stick to using a type of metal and stay away from most liquids when trying to conduct electricity.
Depending on what type of metal the spoon is made out of it is a conductor of electricity. To make the spoon magnetic you would have to constantly charge the spoon with electricity to magnetize the metal base, IE:a nail with a wire coiled around it and charged with two D batteries. All you have to do is coil a wire around the spoon base and connect both ends of the wire(BRASS) to two D batteries and you should have a small electro magnet.
No wood is a poor conductor of electricity. You would want a good conductor (a metal).
