Review of electricity… Charge within an atom comes from: Protons ( ) and electrons ( ) ion = an atom with too few or too many electrons electrons are mobile – can move from molecule to molecule like charges _________ opposite charges __________ Electricity = flow of electrons Electric field = volts of electricity per meter (aligned pos to neg ) – attraction of pos to neg when they are separated. Conductors = materials that contain movable charges (good conductor = water, copper wire (best is silver)) Insulators = materials that are resistant to moving charges (good insulator = air, glass and porcelain)
