Bequerel was the first to note radioactivity, in 1896. Curie discovered radium in 1898, after experiments with uranium and then pitchblende.
Her husband, Pierre Curie, worked with Marie Curie when they discovered Polonium. The Curies also discovered that Thorium, discovered in 1829 by Jöns Jakob Berzelius, emits radiation.
she did not
Marie Curie's discoveries in radioactivity revolutionized the field of science and medicine, leading to advancements in cancer treatment and diagnostic imaging. Her groundbreaking work paved the way for future generations of women in science and inspired a new era of scientific inquiry and innovation. Her legacy continues to inspire individuals to pursue their passions and make meaningful contributions to society.
Marie Curie did not specifically make medicines, but she did conduct groundbreaking research in the field of radioactivity that led to the development of new treatments for cancer, such as radiation therapy. Her work laid the foundation for nuclear medicine and greatly influenced medical science.
The question is nonsense. What constitutes a "discovery"? Is turning over a rock and finding a worm a "discovery"? If you could be more specific ("how many elements did Marie Curie discover?"), then it might be possible to give a sensible answer (two, polonium and radium; on a related topic, she didn't discover thorium, but she was one of the first people to notice that it was radioactive).
Marie Curie discovered radium and polonium and made huge inroads in the research of radioactivity and it's benefits. As a note of interest, both her and her husband Pierre's journals are still radioactive.
Marie Curie did not invent penicillin. Penicillin was discovered by Alexander Fleming in 1928. Marie Curie was a pioneering scientist in the field of radioactivity and made significant contributions to the fields of chemistry and physics.
She made History by discovering radium and potonium
Marie curie was a woman ahead of her time because she did very modern inventions that any other woman wouldn't make in a modern way.
Marie Curie discovered radium in 1898, which played a crucial role in the development of radiotherapy for treating cancer. Radium's radioactive properties were instrumental in pioneering this medical treatment.
