Rutherford concluded that the gold atoms were mostly empty space, which allowed most of the alpha particles through. ... Chadwick bombarded beryllium foil with alpha particles and noticed a neutral radiation coming out. This neutral radiation could in turn knock protons out of the nuclei of other substances.
•In Alpha Ray scattering experiment conducted by Ernest Rutherford, gold foil was taken instead of any other metal because he wanted at least a ray to pass through, while other metals couldn't do that and there could have been complete reboundness. When the experiment was conducted, almost 99% of the days were deflected at several angles, while only some passed through, this gave me an idea that there could be a possibility of presence of some positive centre.
