John Dalton's atomic theory indicated that atoms were indivisible spheres. When JJ Thomson did his work with cathode ray tubes, he discovered that atoms contain electrons, which meant that the atom is not indivisible, that there are smaller particles within.
Thomson's experiment showed that atoms contain subatomic particles, specifically electrons. This discovery led to the modification of Dalton's atomic model, which previously considered atoms to be indivisible and uniform. Thomson's model proposed the existence of electrons within the atom.
The discovery of the electron by J.J. Thomson through his cathode ray tube experiment led scientists to question John Dalton's model of the atom. Thomson's observation of negatively charged particles in the cathode ray, along with their behavior under electric and magnetic fields, contradicted Dalton's indivisible and uniformly dense model of the atom. Thomson's model, proposing that atoms contain subatomic particles (electrons), gained favor due to its ability to explain these experimental findings.
Thomsons model is sometimes called the plum pudding model as he envisaged a soup of positive charge with negative charges, by then already called electrons swimming round. He came up with this idea in 1904."the atoms of the elements consist of a number of negatively electrified corpuscles enclosed in a sphere of uniform positive electrification"Rutherford following on from the famous scattering experiment with gold foil and alpha particles proposed that the positive charge was concentrated in a central nucleus.
The purpose of the Rutherford experiment was to investigate the structure of the atom. By bombarding a thin gold foil with alpha particles and observing their scattering patterns, Rutherford discovered that atoms have a small, positively charged nucleus at the center surrounded by mostly empty space with electrons orbiting around it. This experiment revolutionized our understanding of atomic structure.
Thomson's experiment showed that atoms contained smaller negatively charged particles called electrons, which was not accounted for in Dalton's atomic model. This led to the modification of Dalton's model to incorporate the presence of electrons within the atom. The discovery of electrons also laid the foundation for the development of the plum pudding model by Thomson, which described atoms as a positively charged sphere with embedded electrons.
Thomsons model (plum pudding model of negatively charged particles in a positive soup) differed from Daltons model. Dalton hypothesised that atoms were indivisible, the word atom comes from the Greek atomos cannot be cut)

J.J. thomson's model doesn't have an electrons flowing around like how are planets orbit the sun. The current model has these things.
