These particles are produced in beta minus decay, and this particle's discovery by J.J. Thomson led him to theorize the "plum pudding model.
This particle was first theorized by Richard Laming, and it is the only charged first-generation lepton. One property of this particle was measured by trying to suspend drops of oil in an electric field; that property is the charge, and was first measured by Fletcher and (*) Millikan. These particles are produced in beta minus decay, and this particle's discovery by J.J. Thomson led him to theorize the "plum pudding model." The antiparticle of the positron, for ten points, what is this subatomic particle, which has the opposite charge as a proton?
