For 10 points, name this subatomic particle with charge opposite that of a proton, found orbiting the nucleus of the atom.
The Davisson-Germer experiment scattered these entities, proving their wave-particle duality. The charge-to-mass ratio of these leptons were measured in a cathode ray tube by (*) J.J. Thomson, and their charge was calculated in the oil drop experiment by Robert Millikan.
