WebExperiments with cathode rays led to the discovery of the electron. After measuring the ratio of the charge of a cathode-ray particle to its mass, Thomson concluded that the particles had a very small mass. When an electrical current passed through a glass tube, it caused the surface of the tube directly across from the cathode to glow.
