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
thomas discovered that the atom contained smaller particals called electrons
Thomson's experiments with cathode ray tubes helped him to discover the electron (which Dalton did not know about). Dalton thought that atoms were in.

If i remember correctly, Dalton's focuses more on the nucleus while Thompson's focuses more on electrons. But I'm not sure. well in 1803 John Dalton makes a strong case that atoms are small, solid balls and Joeseph John Thompson discovers electrons, and developed plum pudding model of an atom..... Dalton says that nothings smaller than the atom, but Thompson says that electrons are.
in the grinasals many believed it was wrong
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)
The name for Thompson's atomic model is the 'raisin-bun' model
It was commonly described as a Solid sphere
The plum pudding model was first introduced by J.J. Thomson in 1904 in the March edition of the UK's Philosophical Magazine. It was invalidated 5 years after during what is now known as the Rutherford gold foil experiment, an experiment designed to probe the atom.
He completely changed the model of the atom using his simple alpha scattering experiment.
