1.	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 modelA. (i) and (iii)B. (ii) and (iii)C. (i) and (iv)D. only (i)
Answer» 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.

Answer»

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.
