Question

Which of the following statements is correct about Thomson’s model of the atom?

• A. The mass of the atom is uniformly distributed over the atom
• B. The mass of the atom is concentrated in very small portion of the atom
• C. The size of an atom can be predicted by Thomson’s model of the atom
• D. An atom is elliptical in shape

Answer 1

The correct option is A The mass of the atom is uniformly distributed over the atom

According to Thomson’s model of the atom, the mass and only the positive charge of the atom are uniformly distributed over it so it can’t be said that the charge is uniformly distributed over the atom.
Although, Thomson proposed that an atom possesses a spherical shape but his model can’t predict the size of any atom.
