In the Thomson’s model of atoms, which of the following statemen...
Statement (i): The mass of the atom is assumed to be uniformly distributed over the atom.
- Correct. According to Thomson, the atom is a uniformly distributed mass.
Statement (iii): The electrons are uniformly distributed in the positively charged sphere.
- Correct. Electrons are embedded in the positively charged sphere like "plums in a pudding."

Understanding Thomson's Model of the Atom
Thomson's model, also known as the "plum pudding model," presents a unique perspective on atomic structure. Let's analyze the statements one by one to understand why options (i) and (iii) are the correct ones.
Statement Analysis
Conclusion
Based on the analysis, the correct statements are (i) and (iii). Therefore, the right answer is option b) (i) and (iii).
Thomson's model, also known as the "plum pudding model," presents a unique perspective on atomic structure. Let's analyze the statements one by one to understand why options (i) and (iii) are the correct ones.
Statement Analysis
- (i) The mass of the atoms is assumed to be uniformly distributed over the atom.
This statement is correct. In Thomson's model, the mass of the atom is considered to be spread out evenly throughout the atom, similar to how the dough is distributed in a pudding. - (ii) The positive charge is uniformly distributed over the space.
This statement is misleading. While Thomson did propose that positive charge exists, it wasn't specifically stated that it occupies all space uniformly outside of the electrons. The model primarily focused on a "soup" of positive charge. - (iii) The electrons are uniformly distributed in the positively charged sphere.
This statement is correct. Thomson's model suggests that electrons are embedded within the positively charged "pudding," distributed throughout the sphere, similar to how plums are scattered in a pudding. - (iv) The electrons attract each other to stabilize the atom.
This statement is incorrect. In Thomson's model, the electrons are negatively charged and would repel each other rather than attract. The stability arises from the balance between the negative charge of the electrons and the positive charge of the sphere.
Conclusion
Based on the analysis, the correct statements are (i) and (iii). Therefore, the right answer is option b) (i) and (iii).
