J.J Thomson got to experience with cathode ray tubes that showed atoms negatively charged subatomic particles and electrons. Thomson made the plum pudding model of the atoms.

When he returned from America he achieved his original work of the study of cathode rays culminating and electron. This achievement was made on the evening lecture at the Royal Institution on Friday, April 30, 1897.

He demonstrated that cathode rays were negatively charged. Thomson realized that the accepted model of an atom did not account for negatively or positively charged particles. This ushered in a model of atomic structure referred to as the plum pudding model.The positive and negative charges cancel producing a neutral atom.
