Question

In Thomson’s model of an 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)

Thomson’s model could be compared with a raisin pudding model according to which the mass of an atom is uniformly distributed over the atom in the form of positive charge and electrons are uniformly distributed over the atom. Electrons do not attract each other.
