Which of the following statements about Rutherford’s model of atom are correct?
(i) Considered the nucleus as positively charged.
(ii) Established that the - particles are four times as heavy as a hydrogen atom
(iii) Can be compared to solar system
(iv) Was in agreement with Thomson’s model
Rutherford’s atomic model has the following features:-
i. There is a positively charged centre in an atom called the nucleus. Nearly all the mass of an atom resides inside the nucleus.
ii. The electrons revolve around the nucleus in well-defined orbits which can be compared to solar system.
iii. The size of the nucleus is very small as compared to the size of an atom.
Hence, statement I and iii are correct t.
So, the correct option is A.
