^Rutherford experiment

In 1911 Rutherford, Geiger & Marsden studied the scattering of alpha particles on passing a narrow beam of alpha particles through a thin gold foil. Conclusions of their experimental in 1913 which led to the discovery of the nucleus.

Rutherford’s model discovered nucleus successfully explained the large angle scattering of alpha particles & justified classification of the elements in periodic table but failed to explain about the stability of atom  & also failed to explain the line spectrum of H – atom.
