JJ Thomson Biografi: Mannen som upptäckte elektronen
He demonstrated that cathode rays were negatively charged. In addition, he also studied positively charged particles in neon gas. Thomson realized that the accepted model of an atom did not account for negatively or positively charged particles. Thomson's model showed the atom as a positively charged ball of matter with negatively chaged electrons floating freely around inside of it. This model showed the atom having no structure.

The theory did not mention anything about the nucleus of an atom. It was unable to explain the scattering experiment of Rutherford. Thomson recognized the model that Aristotle made and saw that it was missing a negatively charged electron. He proposed a new model centered around the Plum Pudding model.

In 1897 Thomson discovered the electron. Thomson realized the accepted model of an atom didn't show negative or positively charged particles. He came up with a new model of an atom that resembled plum puddings. This model explained some of the electrical properties of the atom. 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.
