A Dalton's model of atom doesn't exist. Dalton principles are not in agreement with the discovery of isotopes and nonstoichiometric compounds.
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.
One of the best ways to describe John Dalton's observations of elements is that they are made of small particles. The atoms join in simple whole number ratios when the elements react.
John Dalton's atomic theory consists of four key postulates: First, all matter is made up of indivisible particles called atoms. Second, atoms of the same element are identical in mass and properties, while atoms of different elements differ. Third, atoms combine in simple whole-number ratios to form compounds. Finally, during a chemical reaction, atoms are rearranged but not created or destroyed, maintaining their identity throughout the process.
John Dalton introduced the idea that atoms are indivisible and indestructible particles that make up all matter. He proposed that each element is composed of unique atoms with specific weights, which can combine in fixed ratios to form compounds. This marked a significant shift in understanding matter, laying the groundwork for modern atomic theory. Dalton's model emphasized the uniqueness of atoms from different elements and the concept of chemical reactions involving the rearrangement of these atoms.

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.
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

He said that atoms can not be divided; in one matter all the atoms are of same kind,same mass and same type. He also said that different matters have different kinds of atoms. He furthermore said that atoms from different matters meet together at a particular rate and make molecules.
