The Electron.
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.
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.
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.
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.
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.
Electrons
J. J. Thomson is credited with the discovery of electrons.
JJ Thomson discovered electrons, which showed that atoms are not indivisible.
No, the electron
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.

He discovered it 1897.
helped discover atoms an atomic theory
the books he wrote have all the awnsers
Thomson was experimenting with currents of electricity inside empty glass tubes.
