"In 1911 Ernst Rutherferd performed an experiment that showed how charges and masses are are distributed in an atom. J.J. Thomson had hypothesized that the atom was similar to a chocolate chip cookie. Negative electrons (the "chips") nestled in the positive (the "Dough") of the atom in a way that balanced repulsion between like charges and attraction between unlike charges. Rutherford tested this model of the atom by using subatomic projectiles to bombard a target atoms. The projectiles, called alpha particles had been discovered during radioactivity. Alpha particles are high energy positively charged fragments of helium atoms emitted during radioactive decay of unstable elements such as uranium." (Olmsted and Williams chemistry book)
How interesting!
