Answer:
Explanation:
J.J. Thomson was a physicist Who discovered first atomic particle, Electron.
In his cathode ray tube experiment he showed that atoms have small subatomic particles in it which have a negative charge.
This idea led him to think these negative particles are scattered in a pool of positive charges called protons.
This was the basis of Plum pudding model of atom which states that electrons are scattered in an atom just like plums embedded in positive charged pudding.
