John Dalton stated "all atoms of a given element are identical"; discovery of isotopes by Thomson infirmed this old hypothesis.
He formulated his atomic model (electrons orbiting the nucleus) in 1913.
An atomic model of Dalton doesn't exist; the model of Thomson was called plum pudding model.

JJ Thomson's discovery of electrons indicated that atoms were not indivisible.
Before Rutherford, scientists assumed that the atom was a single particle. Rutherford presented his revolutionary, physical atomic model that suggested an atom consists of a central charge (the term 'nucleus' was coined after Rutherford's model was presented) that is surrounded, presumably, by a cloud of orbiting electrons. He showed that most of an atom's mass was located in the atom's nucleus. Rutherford's model was later improved upon by Niels Bohr, father of the Bohr-model. Rutherford made no connection to an element's atomic number and the number of protons within an atom's nucleus; however, his atomic model paved the way for the discovery of this correlation only a couple years after his model was designed.
The atomic models change because scientists have found new evidens dissproving old atomic models and therefore changing them to what they are today although they are still subject to change
The atomic model of today is a quantic model.
The name for Thompson's atomic model is the 'raisin-bun' model
The atomic model cannot be extremely accurate.
