Want this question answered?
Materials that allow energy to flow easily through it are called conductors.
Anything that is classified as a conductor will allow the flow of electrons.
All metals for example iron, copper, nickel. They are called conductors. Plastics and other elements do not, only metals. They allow electricity to pass through them because they have free electrons
Wood An insulator is a material that does not allow charges to move through it easily.
Note that "electricity" doesn't flow, only current does, which is one aspect of electricity, does. Current is the flow of electrons. The main materials that do not allow the easy flow of electrons are rubber, nylon wood, glass, ceramic, plastic and free air.

A conductor. Most metals are conductors-they enable electrons to move freely through them, carrying an electrical charge. Most non-metals (notably excluding graphite, an isotope of carbon) are insulators which means that they do not allow an electrical charge to be carried through them.

insulator...as opposed to a conductor which does allow electrons to travel freely within it.
Conductors are materials that allow electrons to flow easily through it. Metals are the best examples of conductors. Insulators to the opposite; they don't like letting their electrons flow. Glass, rubber, and wood are some examples of insulators.
Isolators.
Those are called insulators.
No, air is not opaque. It is transparent, allowing light to pass through it easily. Opaque materials do not allow light to pass through them.
a brick i think
metals have the ability to pass and conduct electricity and heat through them....
Conductors, a lot of metals are good in conducting (allow transport of) electrons, also ionized acid and salt solutions.
