Which of the following was not proposed by Thomson in his model?
Which of the following was not proposed by Thomson in his model?
The correct option is B Electrons revolve around the nucleus.
In 1898, J.J. Thomson proposed that an atom possesses a spherical shape (radius approximately 10−10m) in which the positive charge is uniformly distributed. Electrons are embedded into it more or less uniformly distributed. Electrons are embedded into it more or less uniformly to give the most stable electrostatic arrangement. This model of the atom is known as plum pudding model or raisin pudding model or watermelon model. This model can be visualized as pudding or watermelon of positive charges with plums or seeds (electrons) embedded into it.
This model assumed that the mass of an atom is uniformly distributed over the atom.
⇒ There was no mention of electrons revolving around the nucleus.
There was no mention of nucleus in his model.
