Rutherford’s Atomic Model-   Before you go through this article, make sure that you have gone through the previous article on Rutherford’s Atomic Model.   We have learnt that- With alpha particle scattering experiment, Rutherford led to the birth of nuclear model of an atom in 1911. But the Rutherford’s atomic model suffered from certain […]

Rutherford’s Alpha Particle Scattering Experiment-   Before you go through this article, make sure that you have gone through the previous article on Rutherford’s alpha particle scattering experiment.   We have learnt that- In alpha particle scattering experiment, the alpha particles were bombarded on thin gold foil. After the collision, the alpha particles were scattered […]

Distance of Closest Approach-   Consider an α-particle moves directly towards the center of an atom. As it approaches the positive nucleus, it experiences a coulombic repulsion and its kinetic energy gets progressively converted into electrostatic potential energy. At a certain distance r0 from the center of the nucleus, the α-particle stops for a moment […]

Alpha Particle Scattering Experiment   Before you go through this experiment, make sure that you have gone through the previous article on Rutherford’s α-particle scattering experiment.   We have discussed- On the suggestion of Rutherford, his two associates Geiger and Marsden in 1911 performed an experiment on the scattering of alpha particles. They obtained an […]

Alpha Particle Scattering Experiment-   On the suggestion of Rutherford, his two associates Geiger and Marsden in 1911 performed an experiment on the scattering of alpha particles and obtained an important insight into the structure of the atom. This led to the birth of the nuclear model of an atom– a major step towards how […]
