The scientists who helped Dalton formulate his model were Antoine Lavoisier and Joseph Louis Proust. Research done by the two formed a basis for Dalton's Atomic Theory.
John Dalton
Dalton proposed planetary model. He kept electrons at a distance.
to create an model
Dalton's atomic model is one of the fundamentals of physics and chemistry. John Dalton named this model after himself.
The Dalton model was created in 1808.
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.

The Australian scientist, M Vella came up with this model in the late 1900's.
Building a model forces a scientist to think about how the parts of the model interrelate and interact with each other. This may help the scientist to formulate better questions about the real system. In addition it is usually far easier to manipulate a model than it is to make changes to a real system so that the implications of those changes can be studied. Once the scientist believes that they understand the model, or suspects that the model has exhausted its usefulness, they can either build a better model or try testing some hypotheses in the read world.
An atomic model from Dalton doesn't exist.
An atomic model of Dalton doesn't exist; the model of Thomson was called plum pudding model.
