Natural polonium was isolated from residues resulted after the extraction of uranium from ores; the process is long and tedious. Today polonium is obtained artificially.

Studying residues of uranium ores Marie Curie found that these residues are more radioactive than uranium; she attributed this radioactivity to an unknown element. She isolated this element and named this element polonium.
Polonium was discovered - not invented !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.
Studying residues of uranium ores Marie Curie found that these residues are more radioactive than uranium; she attributed this radioactivity to a new element. She isolated this element and named polonium.

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

Polonium was discovered by Marie Curie and her husband, Pierre Curie, in 1898. They isolated it from pitchblende ore.
