1.Rutherford’s ‘alpha (α) particles scattering experiment’resulted into discovery of(a) electron (b) proton (c) nucleus in the atom (d) atomic mass.

Describe the most important newunderstanding of the structure of theatom that Rutherford inferred from hisexperiment with alpha particles

The element used by Rutherford duringhis a-scattering experiment.

13.Based on Rutherford’s atomic model, which sub-atomic particle is presentin the nucleus of an atom?A. Proton onlyB. Proton and NeutronC. Neutron and ElectronD. Proton and Electron

An alpha particle is:the nucleus of heliumtwo neutronsan electrona hydrogen atom

In Rutherford experiment a small fraction of  α -particles are scattered at small angle becauseSelect an answerA α  -particles are attracted by a negatively charged particleB α  -particles are pushed towards the heavy nuclear regionC α  -particles are repelled by positively charges regionD α  -particles are attracted by positively charged region
