In the case of metals, because of the attractive force, some free electrons will move through the metal giving the surface of the metal nearest the balloon a negative charge. So the balloon will be attracted towards the metal. helium atom mass

What Is the Best Insulator: Air, Styrofoam, Foil or Cotton?

WebA conductor is a material that allows electrons to flow freely through it, making it useful for carrying electric current. An insulatoris a material that resists the flow of electrons, so it does not allow electric current to pass through it. Learn about how conductors and insulators work and how they are effected by changes in electrical current. WebThere are many materials that can be used to “close” a circuit, or allow current to flow. Materials that allow electric current to flow through easily are called conductors. Most metals including aluminum are good conductors of electricity as well as water.
