Today we continued with discussion about the history of the atom. We learned that when J.J. Thomson discovered electrons trough his experiment with cathode rays, he came up with the a new model of the atom. Thomson called this new model the plum pudding model.
We discussed the Thomson's model is like a chocolate cookie ball or what he coined as the plum pudding model. Here a ball of positively charged particles has embedded in it negatively charged particles. (See the image below.) We read pp. 317-318.
