(D) Rutherford concluded from the $\alpha$-particle scattering experiment that:$(i)$ Most of the space inside the atom is empty because most of the $\alpha$-particles passed through the gold foil without getting deflected.$(ii)$ Very few particles were deflected from their path,indicating that the positive charge of the atom occupies very little space.$(iii)$ $A$ very small fraction of $\alpha$-particles were deflected by large angles,indicating that all the positive charge and mass of the gold atom were concentrated in a very small volume within the atom.From the data,he also calculated that the radius of the nucleus is about $10^5$ times less than the radius of the atom.On the basis of his experiment,Rutherford put forward the nuclear model of an atom,which had the following features:$(i)$ There is a positively charged centre in an atom called the nucleus. Nearly all the mass of an atom resides in the nucleus.$(ii)$ The electrons revolve around the nucleus in circular paths.$(iii)$ The size of the nucleus is very small as compared to the size of the atom.Since all the given options $(A, B, C)$ are correct conclusions derived from the experiment,the correct answer is $D$.

The Rutherford $\alpha$-particle experiment shows that most of the $\alpha$-particles pass through almost unscattered while some are scattered through large angles. What information does it give about the structure of the atom?
