  2. Life of J.J. Thomson • Was born on December 18, 1856 in Cheetham Hill, Menchester. • Study at Trinity College, located in a city called Cambridge in the United Kingdom. • He remand in Trinity College for the rest of his life becoming a Lecturer and a Master there. Later he began to teach at Trinity. • He spent the rest of his life as a professor at Trinity College.

  3. Contribution to Chemistry • Discovered the existence of electrons in atoms. • Discovered the electrical charge of the electrons and how the mass was the smallest particle • Believed the location of the electrons was inside the nucleus • Later the correct location was found without Thomson • This was a new discovery of the atom and open the path way for more discoveries of atoms that had differences.

  4. Experiment • The experiment done by Thomson was done with a Cathode Ray tube which created an invisible electrical ray that would attracted to the opposite side of the tube. • The ray would make a light on the other side of the tube caused by the positively charged plate • When Thomson decided to put a plate with a positive and negative charge on two opposite sides in the middle of the tube the ray would bend toward the positive side of the plate • The only explanation for this was that there most be negatively charged particles in the ray.
