The Curies discovered two radioactive elements: polonium and radium.
Marie and Pierre Curie
Marie Curie. Uranium was discovered in 1789 by the German chemist Martin Heinrich Klaproth working in Berlin.
Polonium was discovered by Marie Curie and Pierre Curie in 1898.Radium was discovered by Marie Curie, Pierre Curie and G. Bemont also in 1898.They are two natural elements, metals, extremely radioactive.
Marie Curie in 1898Radium was discovered by Marie Skłodowska-Curie and her husband Pierre in 1898.
Polonium was discovered by Marie Curie and Pierre Curie in 1898. Radium was discovered by Marie Curie, Pierre Curie and G. Bemont also in 1898. Studying residues of uranium ores Marie Curie and Pierre Curie found that these residues are more radioactive than uranium; they attributed this radioactivity to unknown elements. They isolated these elements and named these elements polonium and radium.
Polonium is a rare radioactive element with symbol Po and atomic number 84. It was discovered by Marie Curie and her husband Pierre Curie in 1898. Radium is another radioactive element with symbol Ra and atomic number 88. It is also discovered by Marie Curie, and both polonium and radium are highly toxic and carcinogenic.

Marie Curie, a pioneering scientist, discovered the radioactive element radium in 1898 along with her husband Pierre Curie. Their discovery of radium marked a major breakthrough in the field of chemistry and earned them a Nobel Prize in Physics in 1903.
