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.
Polonium and radium are radioactive elements and toxic; they are dangerous.
Radium and polonium are principally alpha emitters.
she discovered radium along with her husband Pierre
Any link between Dalton and polonium&radium.
Marie Curie discovered the elements polonium and radium in 1898. She was the first person to isolate polonium and radium from natural sources and conducted groundbreaking research on radioactivity.
- Chemical elements are discovered or prepared, not invented.- Polonium and radium have useful applications.
She invented polonium.

Both radium and polonium are radioactive elements and are not stable.
Polonium and radium are radioactive chemical elements but they have not the same properties.
Polonium (Po) and radium (Ra) are two different chemical elements.
