J.J. Thomson provided experimental evidence of the existence of discrete constituents of matter: He showed that matter has constituents that are negatively charged and whose charge/mass ratio is constant This suggests that charge is not infinitely indivisible but comes in corpuscles (e.g. electrons) In 1894, Thomson began studying cathode rays, which are glowing beams of light that follow an electrical discharge in a high-vacuum tube.

Thompson designed an experiment using magnetism to move the electrons in the opposite direction caused by the electric field. - This allowed him to calculate a charge to mass ratio for the electrons. What conclusion about the electron did he make from this data? Experiment 3.

After the experiments on diffraction of electrons by C. J. Davisson and L. H. Germer, G. P. Thomson, the son of J. J. Thomson, also replicated the experiment on electron diffraction in 1927. Electrons from an electron source were accelerated towards a positive electrode into which a small hole was drilled. In the mid 1800's scientists successfully passed an electric current through a vacuum in a glass tube. They saw a glow from the tube that seemed to emanate f Thomson therefore suggested that atoms are spheres of positive charge in which light, negatively charged electrons are embedded, much as raisins might be embedded in the surface of a pudding. At the time Thomson proposed this model, evidence for the existence of positively charged particles was available from cathode-ray tube experiments. Fig. 1: Schematic setup of the Thomson ring experiment: A capacitor with capacitance C and voltage U0 is discharged through a spiral coil with inductance Lcoil.

Thomson atomic model was proposed by William Thomson in the year 1900. This model explained the description of an inner structure of the atom theoretically. It was strongly supported by Sir Joseph Thomson, who had discovered the electron earlier. During cathode ray tube experiment, a negatively charged particle was discovered by J.J. Thomson.

The electron is a tiny particle, almost two thousand times lighter than the hydrogen atom, and it is negatively charged.
