Question

what. is the difference in the. atommic models of. thomson and rutherford

Answer 1

Since Ancient Greece, scientists have proposed the existence of the atom, but understandings of atomic structures changed rapidly at the turn of the 20th century. This began with J.J. Thomson's 1904 proposal of the plum pudding model, which allowed for an atom of positively charged soup with negative electrons floating throughout. Within less than a decade, scientists Ernest Rutherford and Niels Bohr began to question the model and created the planetary model instead.

Thomson's Plum Pudding Model

In 1904, Thomson proposed the plum pudding model of the atom. The model was named after the consistency of plum pudding with raisins floating throughout. The pudding represented a positively charged filling in which negatively charged electron "raisins" floated. According to the model, the filling was roughly the same consistency everywhere in an atom. Thomson was awarded the Nobel Prize for his theory, and the plum pudding model remained the dominant theory of the atom until around 1908, when it was superseded by the planetary model.

Answer 2

Hi there!

Thompson made a plum pudding/watermelon model in which the electrons were    embedded in a positive sphere. According to him, electrons were stationary.

Whereas Rutherford  did the Alpha scattering experiment of the Cathode Ray tube experiment according to which cathode rays or the negatively charged electrons started moving towards the anode contradicting the Thompson stationary electrons.

Hope it helps u!!
