The development of the atomic theory occurred in multiple stages. In 1803, John Dalton put forward the solid sphere model. He stated that atoms are further indivisible, and the atoms of an element are the same. J. J. Thompson modified the theory and proposed the plum pudding model. As per the model, electrons are scattered around in the atom with a cloud of positive charge.

History of atoms

Rutherford model, description of the structure of atoms proposed (1911) by the New Zealand-born physicist Ernest Rutherford. The model described the atom as a tiny, dense, positively charged core called a nucleus, around which the light, negative constituents, called electrons, circulate at some distance.
