The transitioning of these particles is the basis for the Balmer series.
The first generation of leptons consists of these particles and their respective neutrinos. The transitioning of these particles is the basis for the Balmer series. The positron is the anti-particle of this particle, which emits a photon when it drops in energy level. Robert Millikan determined their charge in the oil-drop experiment. They were first discovered by J.J. Thomson and were the only particle in his "plum pudding" model. For 10 points, name this negatively charged particle that orbits an atom's nucleus.
