DOLTONS ATOMIC THEORY
1)EACH ELEMENT is composed of extremely small particles called atoms.
2)All atoms of a given element are identical.
3)Atoms of different elements possess different properties including atomic masses.
4)Atoms are neither created nor destroyed in chemical reaction.
5)Atoms of elements take part to form molecules.

Thomsons atomic model
1) An atom consists of a positively charged sphere and the electrons are embedded in it.
2) The negative and positive charges are equal in magnitude . So the atom as a whole is electrically neutral.
