Polonium was discovered by Marie Curie and her husband, Pierre Curie, in 1898. They isolated it from pitchblende ore.
Bequerel was the first to note radioactivity, in 1896. Curie discovered radium in 1898, after experiments with uranium and then pitchblende.
Marie and Pierre Curie isolate radium. On April 20, 1902, Marie and Pierre Curie successfully isolate radioactive radium salts from the mineral pitchblende in their laboratory in Paris. In 1898, the Curies discovered the existence of the elements radium and polonium in their research of pitchblende.
In Paris, France, in 1898. The announcement was made on December 26, 1898. It was isolated from the residues of the uranium ore pitchblende by Marie and Pierre Curie and Gustave Bémont. Pierre died in 1906, and Marie Sklodowska Curie (1867-1934) received the Nobel prize for Chemistry in 1911.
Marie Curie concluded that pitchblende contained other radioactive elements in addition to uranium, as its radioactivity exceeded that of the uranium she had isolated. This led her to hypothesize the presence of previously unknown radioactive substances. Her observations ultimately resulted in the discovery of polonium and radium, further advancing the understanding of radioactivity and its elements.

Radium is an element itself. It was isolated by Marie Curie from Pitchblende, an ore of Uranium.

Marie Curie discovered polonium in 1898, along with her husband Pierre Curie. They isolated the element from pitchblende ore after observing unusual radiation properties. This discovery ultimately led to their pioneering work in the field of radioactivity.
Polonium was discovered by Marie Curie and Pierre Curie in 1898.
Marie Curie discovered radium by isolating it from uranium ore through a series of chemical extraction processes. She and her husband, Pierre Curie, demonstrated that the substance emitted highly energetic radiation, which they named "radioactivity." This groundbreaking discovery ultimately led to the development of the field of nuclear chemistry.
Polonium was discovered by Marie and Pierre Curie in 1898, who were studying the residues of uranium pitchblende (after uranium separation) from Jachymow; the residue has a greater radioactivity than uranium.
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.
