WebElectrons and Electricity. Electricity is the flow of electrons through a conductor, usually in the form of a wire, this flow is called an electric current.In order for this flow to occur, electrons must break their atomic bond (electricity is the flow of electrons, not the flow of electrons and the nuclei they happen to be bonded to). Breaking the atomic bond … WebJul 27, 2009 · The particle responsible for electricity, the electron, has a negative charge.
