Question

Explain the atomic model of thomson?

Answer 1

In Thomson's model, the atom is composed of electrons surrounded by a soup of positive charge to balance the electrons' negative charges, like negatively charged “plums” surrounded by positively charged “pudding”. The 1904 Thomson model was disproved by Hans Geiger's and Ernest Marsden's 1909 gold foil experiment.

Answer 2

Thomson proposed that the atom is a sphere of positive charge and electrons are embedded in it just like berries in Christmas pudding or seeds in watermelon. He said that magnitude of negative charge is equal to magnitude of positive charge which makes an atom stable.
