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.
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 modern atomic model is based on quantum mechanics.
The Rutherford model involve a positive nucleus separated from electrons.
J.J. Thomson's work led to the development of the "plum pudding model" of the atom. In this model, atoms were envisioned as a positively charged "soup" in which negatively charged electrons were embedded like plums in a pudding. This model suggested that the atom was a uniform sphere of positive charge with electrons scattered throughout, providing an early understanding of atomic structure before the discovery of the nucleus.
One weakness of Thomson's atomic model, often referred to as the "plum pudding model," is that it could not explain the results of the Rutherford gold foil experiment. This experiment demonstrated that atoms have a small, dense nucleus at their center, contradicting Thomson's idea of a diffuse distribution of positive charge throughout the atom. Additionally, the model failed to account for the discrete lines observed in atomic spectra, which indicated that electrons occupy specific energy levels rather than being spread uniformly.

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 idea that atoms are indivisible.
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.

see along time ago before dinosaurs walked the earth. the end.

thomas discovered that the atom contained smaller particals called electrons
Dalton's theory was irrelevant to the total compensation of of the Atomic Mass.
Dalton's atomic theory or model was accepted despite errors. This is because his theory provided a logical explanation of concepts and led the way to new experimentations.
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.
