The scientists mentioned here played a major contributory role in the discovery of subatomic particles and determining their properties. They conducted several experiments to prove their hypothesis. Many of them gave a theory that proved to be correct and is followed even now.
John Dalton : He experimented with the deflection of cathode rays by a magnetic field.
Ernest Rutherford : He carried out experiments that measures the scattering of alpha particles by heavy atoms.
