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.
