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:
In the 19th century, Henri Becquerel discovered that some chemical elements have atoms that change: During their change they send out a particle. In 1898, Marie and Pierre Curie called this phenomenon radioactive decay. Becquerel and the Curies were awarded the Nobel Prize in Physics for this discovery, in 1903.
