State the names of Thomson’s atomic model.

Thomson’s atomic model is known as “Plum Pudding Model”. This model assumes atom to be a positively charged sphere where the negatively charged electrons are embedded in it. Electrons are similar to the plums present in the pudding. The total positive charge present in the atom is equal to the total negative charge, making atom electrically neutral.
