[…] For a long period in history, scientists were of opinion that atoms could not be broken further into smaller particles. But things changed after the discovery made by a scientist named J.J. Thomson in the year 1897. In his quest to ascertain the basic structure of an atom, he discovered that atoms are divisible and contain a negatively charged subatomic particle – ‘electron’. To know more about J.J. Thomson’s discovery, click here. […]
