Electrons are elementary particles, the negatively charged particles of our matter. Electrons form the shells of atoms and so define the chemical properties of the elements. The number of electrons in the atom is defined by the oppositely charged protons, which attract the electrons. At the transition of electrons to other shells, photons are emitted or absorbed. Electric current mostly is the flow of electrons in a conductive medium (e.g. copper).
