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.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.
This is a discovery not an invention.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.
Marie Curie and her husband Pierre Curie discovered the elements radium and polonium in 1898 through their work on radioactivity. They were awarded the Nobel Prize in Physics for their discoveries in 1903.
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.
