`alpha`-ray scattering experiment proved the presence of neutrons in an atom.

Rutherford's alpha -particle scattering experiment led to the conclusion that :

In Rutherford's alpha-rays scattering experiment, the alpha particles are detected using a screen coated with

Rutherford concluded from his alpha -ray scattering experiment that there exists a heavy and dense body at the centre of the nucleus .

Describe Rutherford's alpha -ray scattering experimental and mention the observations derived from it. Cite and defect of Rutherford's model of the atom.

Number of the alpha - particle deflected in Rutherford's alpha -scattering experiment varies with the angle of deflection. Then the graph between the two is best represented by.
