Following are the equations of several nuclear reactions that have important roles in the history of nuclear chemistry: 1  The first naturally occurring unstable element that was isolated, polonium, was discovered by the Polish scientist Marie Curie and her husband Pierre in 1898. It decays, emitting Î± particles:
May, 1911: Rutherford and the Discovery of the Atomic Nucleus. In 1909, Ernest Rutherfordâs student reported some unexpected results from an experiment Rutherford had assigned him. Rutherford called this news the most incredible event of his life. In the now well-known experiment, alpha particles were observed to scatter backwards from a gold foil. Rutherfordâs explanation, which he published in May 1911, was that the scattering was caused by a hard, dense core at the center of the atomâthe nucleus. Ernest Rutherford was born in New Zealand, in 1871, one of 12 children.
