![]() ![]() 2 – (a) Schematic Representation of Thomson’s Atomic Model (b) Atomic Model Compared to Plum Pudding Postulates of Thomson’s Atomic Model Hence the name Plum Pudding Model was attributed to Thomson’s Atomic Model.įig. This scientific model was compared to Plum Pudding, where the distribution of Electrons was considered as ‘Plums’ (Raisins) in a positively charged Space which was referred to as Pudding. He also assumed that these Negative ions or Electrons moved in an orbit in a sphere which had equal positive charges. ![]() Thomson’s Atomic Model states that an Atom is electrically neutral and is made up of ‘Corpuscles’ which act as Negative ions. 1 – Introduction to Thomson’s Atomic Model He called the ‘Electrons’ as “ Corpuscles”.įig. His theory states that an Atom is made up of thousands of Electrons and an Electron is 2000 times lighter than Proton. He conducted his experiment using Cathode Ray Tube (CRT). Thomson’ was a great physicist who has the credit of discovering ‘Electrons’ and was awarded Nobel Prize for his discovery. Thomson’s Atomic Model (also called as ‘ Plum Pudding Model‘) explains the inner structure of the atom theoretically. Thomson’s Model, How does Plum Pudding Model Work, applications and limitations. This post will discuss what is Thomson’s Atomic Model, postulates of J.J. ![]() Thomson’s Atomic Model also called as ‘ Plum Pudding Model’ was the most accepted Atomic Model during the year 1904-1910, which emphasized on the inner structure of the Atom. ![]()
