WebIsotope study . Thus, Goldstein's analysis led to the study of isotopes, for example, among many other scientific applications that are currently in full force. However, the scientific community attributes the discovery of the proton to the New Zealand chemist and physicist Ernest Rutherford , in the middle of 1918. WebIt wasn't until 1932 that James Chadwick was able to prove its existence. Chadwick used a version of Rutherford's experiment, using a sheet of beryllium and a paraffin block instead of gold...
