Give the experimental conclusions arrived by Rutherford in the `alpha` scattering experiment or state the postulates of Rutherford atom model.

Explanation

Conclusions ( postulates ) :
(i) The entire mass of the atom is concentrated in the nucleus of an atom.
(ii) The entire change is concentrated in the nucleus rather than being distributed through out the volume of the atom.
(iii) The size of the nucleus is estimated to be of the order of `10^(-15)` And that of the atom of the order `10^(-10)`
(iv) The size of the election is negligibly small and the space between the electron and nucleus, is almost void.
(v) Atom as a whole is electrically neutral .
(vi) Electron is acted upon by a force and hence it is not in a state of state equilibrium.
(vii) To explain the `H_(2)` - Spectrum, Rutherford proposed radiation circular orbits , and stability, he assumed that the centripetal force is balance by the electrostatic force of attraction.
i.e., `(mv^(2))/(r)=1/(4piepsilon_(0))[(Ze^(2))/(r^(2))]`
