Question

In the Thomson’s model of atom, which of the following statments are correct?

1. the mass of the atom is assumed to be uniformaly distributed over the atom
2. the positive charge is assumed to be uniformaly distributed over the atom
3. the electrons are uniformaly distributed in the positively charged sphere
4.  the electrons attract each other to stabilise the atom

Options

• (i), (ii) and (iii)

• (i) and (iii)

• (i) and (iv)

• (i), (iii) and (iv)

Answer 1

(i), (ii) and (iii)

Explanation - 

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.
