J.J. Thomson's experiment, conducted in 1897, resulted in the discovery of the electron as a subatomic particle. By using a cathode ray tube, he demonstrated that cathode rays were composed of negatively charged particles, which he called "corpuscles" (later known as electrons). This finding provided evidence for the existence of smaller components of atoms and led to the development of the "plum pudding" model of atomic structure, where electrons are embedded within a positively charged "soup." Thomson's work fundamentally changed the understanding of atomic theory and laid the groundwork for modern physics.
What else can I help you with?
What experiment did J Thomson do?

When did Charles M. Thomson die?
James Francis Thomson died in 1973.
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.
Who said that 'atoms are negatively charged particles'?
It's J.J. Thomson He had the plum pudding experiment The answer is Thomson
What experiment j.j Thomson do?
He hit plates with light
Why was it important for Thomson to repeat his experiment?
Thomson did the experiment various times to observe if the particles behave the same way. How they did he determined they were the same kind later called electrons.
How did the Thomson's experiment change Dalton's atomic model?
Thomson discovered that the atom contained smaller particles called electrons
He conducted the cathode-ray tube experiment?
J.J Thomson conducted the cathode-ray tube experiment in 1911.
Thomson made his discovery about the atom during an experiment using?
Cathode Rays
How did Thomson's' experiment change Dalton's atomic model?
An atomic model of Dalton doesn't exist; the model of Thomson was called plum pudding model.
What is the result of an experiment?
The result of an experiment is a conclusion.data..?
What is the result of a scientific experiment?
The result of a scientific experiment is the conclusion.
When did Thomson conduct the cathode-ray tube experiment?
At the end of the 1800's
What was John Thomson's experiment for the modern model?
John Thomson's experiment involved studying the properties of cathode rays in a cathode ray tube. By observing the behavior of these rays in the presence of electric and magnetic fields, Thomson was able to determine the charge-to-mass ratio of the electron. This experiment provided important evidence for the existence of subatomic particles and laid the groundwork for the development of the modern atomic model.
