'''Ernest Rutherford''' performed experiments in which he fired alpha particles at thin gold foil. His results showed that the positive charges of an atom are concentrated in its center. This disproved the [[Plum Pudding]] model of the atom.
'''Ernest Rutherford''' (30 August 1871 – 19 October 1937) was a [[Nobel Prize]] winning physicist, who earned fame for the following discoveries:
* 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.
*He was the first person to successfully split the atom, whilst working in Manchester, UK in 1917.<ref>http://www.rutherford.org.nz/biography.htm</ref>
