The electrons accumulate on the iron giving it a negative charge that grows until the electrostatic
attraction starts to pull the Fe+ ions back onto the metal surface, stifling further dissociation. At this
point the iron has a potential (relative to a st

Answer. When is exposed to air a thin surface film of oxide forms, following the oxidation reaction
