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.

∙ 14y agoJ.J.thompson discovered the cathode ray after he discovered electrons, which are negatively charged particles. He performed experiments that involved passing electric currents through gases at low pressure. He sealed the gases in glass tubes fitted at both with metal disks called electrodes. The electrodes were, in turn, connected to a source of electricity. One electrode, the anode, became positively charged. The other electrode, the cathode, became negatively charged. The result was a glowing beam, or a cathode ray, that traveled from the cathode to the anode.

Who identified cathode rays as subatomic particles?
Experiments with cathode rays led to the discovery of the electron.
How did thomas discover the electron?
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.

Why was Millikan's discovery important?
Millikan performed the oil drop experiment where he sprayed a very fine mist of oil and manipulated the falling rate of the oil using x-rays. By doing this, he could measure the electron's charge, a particle previously discovered in the cathode ray tube experiment which effectively determined the mass to charge ratio. Millikan calculated the charge of an electron to be -1.602x10-19 columbs. Therefore, the mass must be 9.109x1031 kg. Since the electron was found to have a negative charge, the implication existed that there must be a positive charge located somewhere in the atom since atoms are naturally neutrally charged.
He conducted the cathode-ray tube experiment?
J.J Thomson conducted the cathode-ray tube experiment in 1911.
Which scientists performed the cathode Ray experiment leading to the discovery of electrons?

What did experiments with cathode rays lead to the discovery of what?
experiments with cathode rays lead to the discovery of the Electron.
Which scientist is credited with discovering the electron?

Did J J Thomson's experiments with cathode rays lead to the discovery of the neutron?
No. JJ Thomson's experiments with cathode rays lead to the discovery of the electron.
The discovery of the electron resulted from experiments using what?
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.
What did j.j Thomson experiment with?
J.J. Thomson discovered the electron studying the deflection of cathode rays.
Thomson made his discovery about the atom during an experiment using?
Cathode Rays
Who performed an experiment with cathode ray tubes?
J. J. ThomsonJ. J. Thomson did the cathode ray experiment where he discovered the existence of electrons.
What did William crookes conclude from cathode rays?
William Crookes concluded from cathode rays that there was something more to an atom. Something that carried an electrical current. This was a mystery at the time. William Crooke's experiment helped pave the way for J.J. Thompson's discovery of the electron.
What did JJ Thomson measure?
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.
Who identified cathode rays as subatomic particles?
Experiments with cathode rays led to the discovery of the electron.
