Answer:
He did this by determining how much the cathode rays were bent when he varied the voltage. He found that the mass of the particles was 2000 times smaller than the mass of the smallest atom, the hydrogen atom. In short, Thomson had discovered the existence of particles smaller than atoms.
Explanation:
J.J. Thomson's experiments with cathode-ray tubes showed that each atom includes tiny negatively charged subatomic debris or electrons. Thomson proposed the plum pudding version of the atom, which had negatively-charged electrons embedded within a definitely-charged "soup."
the electron
In 1897, J.J. Thomson determined the electron by experimenting with a Crookes, or cathode ray, tube. He tested that cathode rays had been negatively charged. further, he also studied definitely charged debris in neon gas.
Thomson, a professor of physics at the college of Cambridge in England, established the life of tiny debris a good deal smaller in mass than hydrogen, the lightest atom. Thomson had located the primary subatomic particle, the electron.
