In Thomson’s model of the atom, often referred to as the "plum pudding model," the atom is depicted as a diffuse cloud of positive charge with negatively charged electrons embedded within it. This model does not provide a clear distinction between the size of the positive and negative charges and suggests that the entire atom is relatively uniform in size.

On the other hand, Rutherford’s model introduced the idea of a dense nucleus at the center of the atom, with electrons orbiting around it. This model indicates that most of the atom's volume is empty space surrounding a small, dense nucleus.

Given these distinctions, the size of the atom in Thomson’s model is **much greater than** the atomic size in Rutherford’s model, as Thomson's model encompasses a larger volume of space due to its diffuse cloud representation, while Rutherford's model focuses on a compact nucleus.

### Final Answer:
much greater than
