Question

Which of the following statement is incorrect according to Thomson's model of an atom?

• A. The electrons, in a sphere of positive charge, were like currants (dry fruits) in a spherical Christmas pudding.
• B. The positive charge in the atom is spread all over like the red edible part of the watermelon.
• C. The electrons are studded in the positively charged sphere, like the seeds in the watermelon.
• D. The protons are studded in the positively charged sphere, like the seeds in the watermelon.

Answer 1

The correct option is D The protons are studded in the positively charged sphere, like the seeds in the watermelon.

Thomson proposed the model of an atom be similar to that of a Christmas pudding. The electrons, in a sphere of positive charge, were like currants (dry fruits) in a spherical Christmas pudding.

One can also think of a watermelon, the positive charge in the atom is spread all over like the red edible part of the watermelon, while the electrons are studded in the positively charged sphere, like the seeds in the watermelon.
