John Dalton put forward the idea that each element is made of a different sort of atom. Each kind of atom had its own properties such as an individual mass.

when compairing the two you will realise that the greek theory was very limited, due mainly to the lack of tecknolagy and there scintific outlook on the world being primative and based on elemental factors such as water fire earth wind ex. daltons theary on the other hand was far more complex and based on experamentle data rather then simply reasoning as the greek was. basicaly the greek atom was simple and only theary , while daltons had proof and was complex, or atleast more so then the original greek model.
the theory which states that all matter is made up of indivisible particles, called atoms, which combine to form molecules; formed by john Dalton in the year 1803
John Dalton discovered the atom in 1803. He didn't really discover the atom. He developed a theory of matter that involved atoms. Atoms were proved to exist later.
1808
Thomson's discovery of the electron showed that there were things smaller than the atom that could be removed from the atom. Therefor the atom was not an "uncuttable" object as Dalton had proposed.
