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
Radium and polonium are radioactive natural chemical elements.
Marie Curie and Pierre Curie found after studying residues of uranium ores 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.

Radium and polonium have many applications but they are not so important to affect us today.
Polonium and radium's affect on our lives today are for example the meters on our cars, they glow because of the radium and also some wristwatches the light you get when you press the button on the side. Radium was discovered by a woman named Marie Cuire, she's married, but she obviously died because of too much radium.
Radium and polonium are radioactive natural chemical elements.
For radium and polonium the word "invented" is not correct; you must use "discovered".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.
Yes, radium and polonium are radioactive elements.
Polonium and radium are radioactive elements and toxic; they are dangerous.
Polonium and radium doesn't affect history.
Radium and polonium doesn't changed the world.
Radium and polonium are principally alpha emitters.
Marie and Pierre Curie discovered that polonium and radium are natural radioactive chemical elements. 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.
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.
