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:
Discovery of Zirconium. Precious stones containing zirconium, such as hyacinth and zircon, have been used as decorations since ancient times. Zirconium was first recognized as an element by Martin Heinrich Klaproth in 1789, in Berlin, in a sample of zircon (zirconium silicate) from Sri Lanka. His analysis of the mineralâs composition showed: 25% silica; 0.5% iron oxide; 70% new oxide. He called the new oxide âZirconerde.â (2)
