In Rutherford's gold foil experiment, the scattering of alpha -particles takes place. In this process:

Assertion : In Rutherford's alpha -particle scattering experiment, most of the alpha -particles were deflected by nearly 180^(@) . Reason : The positive charge of the atom is spread throughout the atom that repelled and deflected the positively charged alpha -particles.

In Rutherford's gold foil experiment most of the alpha -particles pass through the gold foil without any deviation from their paths . This indicates that

In Rutherford's scattering experiment of alpha -particles by metallic foils, with the increase of atomic number of nucleus, the scattering angle .
