The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Thomson Model**: The Thomson model of the atom, also known as the Plum Pudding model, suggests that an atom is composed of a positively charged "pudding" with negatively charged electrons (the "plums") embedded within it. 2. **Mass Distribution in the Atom**: According to this model, the mass of the atom is assumed to be uniformly distributed throughout the atom. This means that the positive charge (the pudding) and the electrons (the plums) are spread out evenly. 3. **Conclusion**: Therefore, in the Thomson model, the mass of the atom is assumed to be uniformly distributed. 4. **Final Answer**: The mass of the atom is assumed to be uniformly distributed according to the Thomson model. ---
