Question

Thomson compared atom to watermelon (or plum pudding) and thus derived some conclusions.Which of the following are his conclusions?

• A. The seeds are positive spheres and red edible parts are the electrons
• B. The seeds are the electrons and red edible part is the positive sphere
• C. The seeds and edible part both are electrons
• D. The seeds and edible part both are positive charges.

Answer 1

The correct option is B

The seeds are the electrons and red edible part is the positive sphere

Thomson’s model of an atom describes that the electrons are like seeds in a sphere of positive charge, which is the red edible part of the watermelon.

This can also be explained with a plum pudding model.
