Describe thomson's cathode ray experiment and how the experimental results led to specific changes in the accepted model of the atom. be sure to include a description of the atomic model that was accepted by the scientific community before this experiment as well as the atomic model that was accepted after this experiment. (4 points)

In his experiment, Thompson shot a beam of alpha particles at a sheet of gold foil, and only a few of the particles were deflected or reflected right back. Before the experiment, the plum pudding model was believed to be true, where a cloud of positive ions distributed throughout the inner space of an atom. Thompson concluded that there's a high-energy dense nucleus at the center of an atom.

They are all solids.
