Background of Thomson’s Atomic Model
The first scientific discussion about the structure of atoms was started by famous scientist JJ Thompsom in 1897. He stated that atoms are spherical shape objects in which electrons are embedded in a jelly-like substance and the jelly-like substance is called protons. Initially, scientists are of the view that atoms are indivisible and they did not believe the explanation of Thomson stating that atoms are made up of smaller particles. This was proved later by his cathode ray experiment which proved that atoms are made up of negatively charged particles called Electrons.
Thomson Atomic Model is not the most accurate model to explain the structure of an atom as it has various drawbacks but it was the first model to explain the basic structure of an atom that atom as a whole is neutral and it consists of positive and negative charge in equal magnitude. After Thomson, various scientists proposed the atomic structure which was further enhanced to get the idea of the atom which prevails today.

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.
