Q. 54.5( 2 Votes )

Rutherford’s α- particle scattering experiment showed that:

(i) Electrons have negative charge

(ii) The mass and positive charge of the atom is concentrated in the nucleus

(iii) Neutron exists in the nucleus

(iv) Most of the space in atom is empty

Which of the above statements are correct?
A. (i) and (iii)

B. (ii) and (iv)

C. (i) and (iv)

D. (iii) and (iv)

Answer :

The conclusions drawn by Rutherford from alpha particle scattering experiment are:-

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.

iii. The size of the nucleus is very small as compared to the size of an atom.

Hence, statements ii and iv are correct and the correct option is B.
