Gold metal is bombarded with alpha rays in Rutherford's model of an atom.
The nucleus was discovered by an alpha scattering experiment. Rutherfords used gold foil and observed that most of the alpha rays pass undeflected but some are deflected due to repulsion by a positive charge in small nuclei at the centre of an atom.
