Jj thomson atomic model description

Following his discovery of the electron in 1897, British Physicist J.J. Thomson proposed a model of the atom in 1904 after doing a series of cathode tube experiments.

According to his hypothesis, an atom consists of positive and negative charges present in equal amounts so that it is electrically neutral.

He proposed that the atom was a sphere with charges embedded within it. This model became known as Thomson Atomic Model ^[1-4].

Later models established that the atom consists of a nucleus having positively charged protons and neutral neutrons, with negatively charged electrons surrounding the nucleus.

Nevertheless, Thomson’s model is significant because it introduced the idea that an atom consists of charged particles.

It envisioned electrons being enclosed within a uniform sphere of positive charge, similar to blueberries inserted into a muffin.

The positive substance was likened to jelly or a thick soup, and the electrons were believed to possess some de
