Briefly describe Rutherford's experiment that led to the discovery of the atomic nucleus.

In 1911, Ernest Rutherford executes an analysis and research to test the plum pudding model. He fired energetic  [He2+] elements at a foil and calculated the deflecting particles as they came on the other side. From this, he could conclude information about the framework of the foil. Therefore, Rutherford discovered the nucleus.
