Rutherford's Nuclear Model


(1) Rutherford carried out experiment on the bombardment of thin (10–4 mm) Au foil with high speed positively charged α- particles emitted from Ra and gave the following observations based on this experiment,

   (i) Most of the α- particles passed without any deflection.

   (ii) Some of them were deflected away from their path.

   (iii) Only a few (one in about 10,000) were returned back to their original direction of propagation.

         

(2) From the above observations he concluded that, an atom consists of

   (i) Nucleus which is small in size but carries the entire mass i.e. contains all the neutrons and protons.

   (ii) Extra nuclear part which contains electrons. This model was similar to the solar system.
