WebConclusions: Thomson concluded that the rays were negatively charged and moved around the positive charge. The characteristics of these rays do not depend upon the nature of the electrode material or the nature of the gas-filled tube. He concluded that the atom can be divided into smaller particles. An atom consists of negatively charged ... Thomson discovered this through his explorations on the properties of cathode rays. Thomson made his suggestion on 30 April 1897 following his discovery that cathode rays (at the time known as Lenard rays) could travel much further through air than expected for an atom-sized particle.
