Observations of Thomson’s Atomic Model
Thomson’s Atomic Model, also called the Plum Pudding Model states that an atom can be compared to a plum pudding where electrons are like dry fruits in a sphere of positive charge, representing the pudding. We can also compare this with a watermelon where the positive charge is comparable to the edible part of the watermelon, and electrons are like seeds that are embedded in that sphere.
The diagram explaining the Plum Pudding Model or the Thomson Atomic model is added below which shows that positive charge is spread throughout the atom and negative charge is embedded in the atom maintaining the electrical neutrality of the atom.
Thomson’s Atomic Model
Thomson’s Atomic Model is one of the fundamental models of the atom that tries to explain the working and structure of the atom. this model was proposed by famous Scientist JJ Thomson in 1904. Thomson during his cathode ray experiment proved the existence of a negatively charged particle called electron that exists inside the atom. And after complaining about his result he prosed the Thomson atomic model also called Pulm Pudding Model.
In this article, we will learn more about, Thomson Atomic Model, its postulate, and its limitations in detail.
