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.
Metals. Which is why metals are good conductors of electricity.
Conductors can allow electricity flow through them as the electrons within their atoms move between atoms easily. Examples of conductors include copper, aluminum, gold and zinc.
A conductor!
It should always be a material which has lots of free electrons .
Electrons can move easily in metals.
conductor
Metals are materials in which particles (electrons) can freely move. If you mean bigger particles (such as atoms or molecules), then liquids and gasses allow easy movement
"semipermeable"
As free electrons move on the surface of a metallic substance, they can form electric currents. Metals function as good electrical conductors. An important property of a metal is its ability to conduct both heat and electricity. Metals easily lose electrons from the outer shell of their atoms, and those electrons are free to move around. Conductivity measurements provide an estimate of electron mobility.(Text taken from eHow.)
when electricity is passed throug inert gas like Neon,it liberates its electron and this electrons can allow elecricity to pass through it.
insulator
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.
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.
Those are called insulators.
Isolators.
a brick i think
metals have the ability to pass and conduct electricity and heat through them....
radiation
Conductors, a lot of metals are good in conducting (allow transport of) electrons, also ionized acid and salt solutions.
no
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
