Explanation:

1. He had the opportunity to have a chance of doing experimental research where he began to develop a theory on electromagnetism. He was then recognized in 1884 and appointed to chair of physics at Cavendish Laboratory. In 1914 there was a new type of physics that lead to more questions than there were answers for and that is when Thomson began associating himself with this new type of physics.

2. Thomson began experimenting with the cathode ray tubes that showed him that all atoms contain small negatively charged particles/electrons. His proposition to the atom was shown with is plum pudding model, which showed negatively charged electrons that were embedded in a positive charge. His discovery came before the discovery of the atomic nucleus that would be included in the electron in the atomic model.

3.His contributions to the atomic model include that all matter is made of atoms, atoms are invisible and indestructible, all atoms in a certain element are identical, two or more atoms that are combined form a compound, and a chemical reaction is the rearrangement of the atoms. His ideas of the atomic model that do not exist in the modern day atomic model include the fact that the distribution of the negative and positive particles was not uniform.
