Question

Winch of the following statements is not true about Thomson's model of atom?

• A. This model can be visualized as a pudding or watermelon of positive chargewith plum or seeds as electrons embedded into it.
• B. The mass of the atom is assumed to be uniformly distributed over the atom.
• C. An atom possesses a spherical shape in which the positive charge is uniformlydistributed.
• D. This model could not explain the overall neutrality of the atom.

Answer 1

Answer: (D)

This model could not explain the overall ncutrality of the atom, because he proposed that the positive charge is spread over a sphere in which the electrons are embedded to make the atom as a whole neutral, but it was not consistant with the results. Hence, discarded.
