Crookes observed that the cathodic rays are deflected by a magnetic field and concluded that this beam is negatively charged. Thomson established that the beam is composed from a new type of particles called by Fitzgerald electrons. Thompson also believed that electrons float in a "pudding" of positive charges.
J. J. Thomson discovered the electron using an experiment involving cathode rays and a magnetic field. When subjected to the magnetic field, the cathode ray was deflected. If the magnetic field was flipped, the cathode ray was deflected in the opposite direction. This proved that a cathode ray was a stream of negatively charged particles that would later be deemed electrons.
J.J. Thomson is credited with identifying cathode rays as streams of negatively charged subatomic particles, which were later named electrons. His experiments with cathode ray tubes led to the discovery of the electron and contributed to the development of the atomic theory.
Thompson's cathode ray experiment led to the discovery of the electron, which was a fundamental particle in the atom. This challenged the earlier model of the atom as a solid, indivisible sphere by proposing a structure of a positively charged sphere with negatively charged electrons embedded within it. Thompson's model contributed to the development of the modern atomic model.
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.

it was electrons
J.J Thompson discovered the electron. He also performed the Cathode Ray Tube Experiment and that told him that electrons are negative J.J Thompson discovered the electron. He also performed the Cathode Ray Tube Experiment and that told him that electrons are negative
his important work was cathode ray experiment . he also discovere the natural radioactivity of pottassium.In his second experiment, he investigated whether or not the rays could be deflected by an electric field.in the third experiment he measured the mass to charge ratio of cathode rays by measuring how much they are deflected and how much energy they carries.
There were no technologies. The atom was discovered by the ancient Greek's. They figured that eventually if you kept on dividing something, it would get so small that you wouldn't be able to divide it anymore. There would be just one tiny particle left. They called this particle the atom. Of course over time the atom proved not to be the smallest particle with the discovery of the proton, electron and neutron.
J.J. Thomson experimented with cathode rays in a vacuum tube, which led to the discovery of the electron in 1897. By measuring the charge-to-mass ratio of electrons, he determined that they were a fundamental particle and were present in all atoms.
He hit plates with light
