jan 1, 1897 - Thomson's Contribution to the Atom

Description:

Thomson made one of the biggest discoveries out of the philosophers. Thomson was able to discover electrons by experimenting with a cathode ray tube. He demonstrated that cathode rays were negatively charged. His model was also described as the "Plum Pudding or Blubbery Muffin Model". It was called this because the positive mater acted as the muffin or pudding, and the negatively charged electrons acted as the blueberries or crumbs.
