Which of the following statements about Rutherford’s model of atom are correct?- considered the nucleus as positively charged
- established that the α–particles are four times as heavy as a hydrogen atom
- can be compared to solar system
- was in agreement with Thomson’s model
(a) (i) and (iii)
(b) (ii) and (iii)
(c) (i) and (iv)
(d) only (i)
Correct Answer: (a) (i) and (iii)
Explanation: According to the Rutherford model, a central positively charged nucleus is present in the atom and electrons revolve around it. This model is similar to the solar system so also called the planetary model.
