Operation Terminology


An electron is a stable, elementary, negatively charged particle. Electrons have the smallest amount of mass of all the subatomic particles. Electrons may be in bound states around nuclei where they determine chemical properties of elements, may radiate through space as electron beams, or through conductors to form an electrical current. Electrons are spin 1/2 fermions and interact via the electromagnetic and weak forces.
