Radium is a chemical element
Polonium is a chemical element
Those two were discovered by Marie Curie
she dicovered in 1898 two new radioactive elements; polonium and radium.

Marie Skłodowska Curie and her husband Pierre discovered the elements polonium and radium in 1898, and named polonium for her native country Poland.

Polonium and Radium
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 and Pierre Curie found after studying residues of uranium ores 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.
Actually, they didn't discover it(a scientist named Wilhelm Roentgen did.). they researched on it, and discovered radium and polonium, two radioactive elements. marie and pierre won a nobel prize in chemestry for it.

Polonium and Radium
Pierre Curie and his wife Marie Curie discovered two new elements and helped bring in a new age of science. Together they also discovered that radioactive elements turned into different elements over time. Pierre and Marie Curie shared the 1903 Nobel Prize with Henri Becquerel in physics. After he died, Marie won the Nobel Prize in chemistry in 1911.

Marie Curie invented two new elements, radium and polonium. She also invented the term 'radioactive' to describe these new elements. With her help doctors were able to cure specific types of cancer. She won two Nobel Prizes for her work. marie curie rox... *k@yl@*
The question is nonsense. What constitutes a "discovery"? Is turning over a rock and finding a worm a "discovery"? If you could be more specific ("how many elements did Marie Curie discover?"), then it might be possible to give a sensible answer (two, polonium and radium; on a related topic, she didn't discover thorium, but she was one of the first people to notice that it was radioactive).
