In the cathode ray tube experiment, J. J. Thomson passed an electric current through different gases inside a cathode ray tube in the presence of an electric field. In which two ways did this experiment change scientists’ understanding of the atom?

The Experiment of the JJ Thomson told the scientists that the atom is not indivisible but it consists some charged particles which are named as electrons.
He also told that the atom is electrically neutral which contains the same number of the electrons and same number of the protons.
These two were the main conclusions of the cathode ray experiments which changed the scientist views against the atoms.
Note ⇒ In case of the Cathode ray experiment, Potential was maintained about 5000 Volt and pressure was reduced to 10⁻³ mm of Hg so that it becomes conducting for the Cathode ray.
Hope it helps.
