Early research on radioactivity
One of the first scientists who do researches on the phenomenon of radioactivity, in those days just discovered, was Ernest Rutherford (Nelson 1871 - 1937 Cambridge) who managed to discover that the process was mainly caused by the enactment of radioactive particles from ionizing atoms that have this type of feature, and then each ionization process results in the transformation of the atom. Studies by Rutherford and his collaborators in the famous Cavendish Laboratory came to find that the structure of the atom should be of global and then with a core in a compact space of positive charge and gravitated around long-distance (in relationship with the dimensions) electrons of negative charge, then practice in using the method of "alchemical" type devised by Marie Sklodowska Curie was able to obtain the transformation of the matter by splitting atoms.
