Thomson's atomic model

 Thomson's Atomic Model

After the discovery of electron and proton J.J Thomson in 1898 tried  to explain the arrangement of a electron and proton in an atom. He proposed that an atom is consist of a spear of positive electricity  in which the electron  are embedded  like plum-pudding or seed evenly distributed in the red spongy mass of a watermelon .

👉 Thomson model of atom is also called as plum-pudding model because it just like raisins in the pudding.

👉The model able to explain some know text or properties of atom like electrically neutrality of atom.

👉It could not satisfy the experimental text and hence it was discarded .

Limitation

👉It could not explain the ionisation and scattering experiment performed by rutherford .
