Yes, radium and polonium are radioactive elements.
Marie currie
No. The Curies did not discover uranium. They discovered polonium and radium, of which polonium is more radioactive.
Polonium is a rare radioactive element with symbol Po and atomic number 84. It was discovered by Marie Curie and her husband Pierre Curie in 1898. Radium is another radioactive element with symbol Ra and atomic number 88. It is also discovered by Marie Curie, and both polonium and radium are highly toxic and carcinogenic.
She discovered the elements Polonium, which was named after her homeland, and radium. Polonium is 4x more radioactive than uranium and radium is 10x more radioactive than uranium.
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.
The Curies discovered two radioactive elements: polonium and radium.
Radium and polonium are radioactive natural chemical elements.
Polonium and radium are radioactive elements and toxic; they are dangerous.
Radium is a radioactive element that was discovered by Marie Curie and her husband, Pierre Curie. It was used in the past for medical treatments and in luminescent paints. Polonium is another radioactive element discovered by Marie Curie, named in honor of her home country of Poland. It is highly toxic and was used as a heat source in early space missions.
Both radium and polonium are radioactive elements and are not stable.
Radium is a chemical element Polonium is a chemical element Those two were discovered by Marie Curie
Polonium and radium are radioactive chemical elements but they have not the same properties.
