Thomson assumed atom to be a spherical body in which:
The electric field used in Thomson's experiment had a strength of If a cathode ray particle with a mass of and a charge of was deflected by an angle of 30 degrees in the electric field, what was the speed of the particle before entering the field?
This model was proposed by J.J Thomson in 1898. According to this model, the atom possesses a spherical shape in which a positive charge is uniformly distributed and the electrons are embedded into it in such a manner that it gives the most stable electrostatic arrangement. This model is also known by various names like plum pudding, raisin pudding or watermelon. One important feature of this model is that it could explain the overall neutrality of the atom but it was not consistent with the results of experiments carried out later by different scientists.
