The very early discovery of particles that were subatomic was proposed by Dalton, which was then negated by the postulates suggested by Thomson that proved Dalton's theory.
<u>Explanation:</u>
The structural arrangement of atoms were approved by Thomson and Rutherford using the technique of air condition in x-ray showing the arrangement of protons and neutrons within Centre.
A nucleus and the negative particles that we called electrons moving around which were also shown to be much lighter than the particles present in the centre.
