Radium and polonium are radioactive natural chemical elements.
Yes, radium and polonium are radioactive elements.
Polonium and radium are radioactive elements and toxic; they are dangerous.
The discovery (not invention) of polonium and radium didn't changed the history.
Both radium and polonium are radioactive elements and are not stable.
Of course, many scientists worked with radium and polonium.
The discoveries of radium and polonium doesn't affect the atom model.
Polonium and radium are radioactive chemical elements but they have not the same properties.
Polonium (Po) and radium (Ra) are two different chemical elements.
Polonium and radium are natural chemical elements, metals, solid, very radioactive.
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.After this discovery the properties of both elements were studied by many scientists.
Radium is a chemical element Polonium is a chemical element Those two were discovered by Marie Curie
