J J thomson is credited with the discovery of the electron. Following some ground breaking research he determined that the electron had a negative electrical charge and had mass.
He modelled the atom as electrons orbiting in "sea of positive charge" setting the scene for experimental veification of this idea. This of course was NOT forthcoming as Rutherford soon afterwards got the then suprising result that there was a nucleus at the centre of the atom.
Without his insights into the nature of the lectron the development of chemistry and physics would have been delayed.

What particles did jj Thomson discover?
J.J. Thomson discovered the electron in 1897 while conducting experiments with cathode rays. This discovery was groundbreaking as it provided evidence for the existence of subatomic particles.
Did J.J. Thomson discover isotopes?
No, J.J. Thomson did not discover isotopes. Isotopes were discovered by Frederick Soddy and John William Strutt in the early 20th century. J.J. Thomson is known for his discovery of the electron.
What did Thomson used a cathode ray to discover the what?
J.J. Thomson used a cathode ray to discover the electron in 1897. Through his experiments, he demonstrated that cathode rays were composed of negatively charged particles, which were much smaller than atoms. This groundbreaking discovery led to the understanding of atomic structure and the development of the field of particle physics. Thomson's work fundamentally changed the perception of matter and laid the groundwork for modern atomic theory.
