Question

In Thomson's model of the atom, which of the following statements are correct?
(i) The mass of the atom is assumed to be uniformly distributed over the atom.
(ii) The positive charge is assumed to be uniformly distributed over the atom.
(iii) The electrons are uniformly distributed in the positively charged sphere.
(iv) The electrons attract each other to stabilize the atom.

• A. (i), (ii) and (iii)
• B. (i) and (iii)
• C. (i) and (iv)
• D. (i), (iii) and (iv)

Answer 1

The correct option is A (i), (ii) and (iii)

According to Thomson, the model of an atom is similar to a Christmas pudding.

The electrons are studded like currants(decorated) in a positively charged sphere like Christmas pudding and the mass of the atom was supposed to be uniformly distributed.

Therefore (i), (ii) and (iii) are all correct.

Hence the correct option is A.
