Which of the following is not another name for Thomson’s model of the atom?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Nuclear model
In Thomson’s model, the atom is a sphere of positive charge with electrons embedded in it, like seeds in a watermelon or raisins (plums) in a pudding; hence the names plum pudding, raisin pudding and watermelon model. The nuclear model is Rutherford’s model, in which the positive charge and almost all the mass are packed into a tiny nucleus at the centre.
