who discovered radium and polonium
Radium, in the form of radium chloride, was discovered by Marie Curie and Pierre Curie in 1898. They extracted the radium compound from uraninite and published the discovery at the French Academy of Sciences five days later.
She then figured out that pitchblende must contain another highly radioactive element, yet unknown. The idea of ââa new element was so exciting to her husband Pierre that he put his own research aside and helped Marie. In 1898, they discovered two new elements-polonium and radium. Polonium was named after Marie's homeland, Poland. Radium got its name from the Latin word for ray. Radium hands from 1940-1950's watches.
