Is copper a good insulator? How is a conductor different from an insulator? Which materials are the best thermal insulators? Is it possible to charge an electrical insulator? Is styrofoam an amorphous solid? Where does the charge go on an insulator?
Copper is classified as a transition metal on the periodic table of elements and has the atomic number 29. This means that an atom of copper will have 29 protons in its nucleus. A renewable resource is a naturally-occurring resource that will replenish itself through natural processes, ...

Paper is an insulator of both heat and electricity, meaning that it does not conduct either of them. This is because it does not allow the free flow of electrons. However, some types of paper, such as those containing metal particles, may be slightly mor

The opposite of an insulator is a conductor--a material with a low resistance and a high conductivity to electrical current or heat. Metals are considered conductors because their electrons are not tightly bound, allowing the flow of both electricity and heat. Copper is the most widely used con...
