She didn't invent radioactivity, she developed an explanation of it.
She didn't. The main thing she studied was radioactivity.
She discovered radioactivity and the elements Radium and Polonium!
She invented a new era for medical knowledge and diseases
no but she built the knowleage of radioactivity.
Marie Curie did her studies of radioactivity with her husband Pierre Curie and with their associate Henri Becquerel.
Curie's efforts, with her husband, Pierre Curie, led to the discovery of polonium and radium and, after Pierre's death, the development of X-rays.
NO. Henri Becquerel was the discoverer of radioactivity.
Marie curie...
Marie Curie (although she did not 'discover radioactivity'; that was Becquerel)
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.

No, it was discovered by Marie and Pierre Curie. Other scientists also contributed, such as Henri Bequerel. (Bequerel is the S.I unit for radioactivity). No, Marie Curie discovered and named radioactivity. Sadly her research into radiation caused her death.
