What did the scientist Thomson discover?
J.J. Thomson discovered the electron in 1897. He conducted experiments with cathode rays that led him to propose the existence of these tiny, negatively charged particles. Thomson's discovery laid the foundation for our understanding of the structure of atoms.
Why did jj Thomson do his experiment?
J.J. Thomson performed his experiment to discover the existence of subatomic particles known as electrons. By studying the properties of cathode rays, he was able to determine the charge-to-mass ratio of electrons and propose the plum pudding model of the atom.
Did Dalton discover electrons?
No, John Dalton did not discover electrons. The existence of electrons was proposed by J.J. Thomson in 1897 through his experiments on cathode rays. Dalton, on the other hand, is known for his work on atomic theory in the early 19th century.
When did JJ Thomson discover the electron?
J.J. Thomson discovered the electron in 1897 while conducting experiments on cathode rays. He observed that these rays could be deflected by electric and magnetic fields, leading him to propose the existence of a negatively charged particle within the atom, which he named the electron.
How did J.J. Thomson discover negative charges?
J.J. Thomson discovered negative charges by studying cathode rays in a vacuum tube, where he observed that they were deflected by electric and magnetic fields in a way consistent with negatively charged particles. This led him to propose the existence of negatively charged particles, which he later named electrons.
What particle did Thomson discover?

What did Thomson discover in the atom?
JJ Thomson discovered electrons, which showed that atoms are not indivisible.
Did JJ Thomson discover the proton?
No, the electron
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.
