After J.J. Thomson discovered electrons using cathode ray tubes, scientists proposed the plum pudding model of the atom, which depicted atoms as a positive sphere with embedded electrons to achieve electrical neutrality. However, this discovery created a new scientific mystery: if atoms contain negative electrons, where does the positive charge originate? This question drove further experimentation with cathode ray tubes, leading scientists to search for the source of positive charge within atoms.

What Happened After the Discovery of the Electron? ⚛️🔍Added:
after the discovery of electrons by J.J.
Thomson. And he used the cathode rays tube as well.
At that time, the people start believing that the atoms look like this. They have a positive big circle with electrons embedded in them in such a way that atom doesn't have any charge on it.
But at that time, scientists also began searching for the source of positive charge. Like, where is that positive charge?
And they would keep using this cathode rays tube for more experiments.
