* He explained the perplexing problem of radioactivity as the spontaneous disintegration of atoms (they were not necessarily stable entities as had been assumed since the time of the ancient Greeks),  

*He determined the structure of the atom and showed that the positive charges of an atom are concentrated in its center.  This disproved the [[Plum Pudding]] model of the atom.
