How did Marie Curie know that she had discovered a new radioactive element?
Her research did not lead to the atomic bomb. The only thing that she discovered that was used in the early atomic bombs was the element polonium (in the neutron source initiators), and it was replaced later with electrically activated tritium fusion neutron sources.Her research did foreshadow some of the radiation burns, etc. experienced by survivors of the atomic bombings though.
What equipment did Marie Curie use when discovering polonium and radium?
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.
What did Marie Curie Do In The World?
Marie Curie was a polish scientist who discovered both radium and polonium. She defined their atomic weight and place on the periodic system, and she was the first to discover methods for extracting pure Radium salts and metal. She founded radioactivity, used for xrays in the world today.
What did Marie curie do for a living?
Marie Curie discovered radium and polonium with her husband, Pierre Curie. This lead to the radiation therapy, which is a therapy used for treating diseased cancer cells by putting radiation on the cancer cell.
How did Marie Curie improve the world of science?
She found out many things in science like, she found out two new elements in the periodic table. She soon became famous and scientists all over the world came to visit her.
What element is radioactive and discovered by the Curies?
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.

What equipment did Marie Curie use to discover polonium and radium?
She used an electrometer.
Who discovered that radium could be used to treat diseases?
Marie Curie

How did Marie Curie's work impact society?
Her discovery of radium changed the way people look and try to treat cancer. Radium is used in x-rays and polonium is used in many drugs, like tobacco. Marie Curie has contributed all these things to the society.
How is Marie Curie significant?
Marie Curie coined the term "radioactive" and she discovered two new elements, polonium and radium. She realised that radioactivity could be used to destroy cancerous tissue, after noting that her fingers burned while handling radioactive uranite, but healed afterwards, suggesting tissue could be destroyed, but was then replaced.
What chemical did Marie Curie use to separate ore?
The process for the separation of radium and polonium from ores is long and difficult; many chemicals were used.
What did Marie curie do for a living?
Marie Curie discovered radium and polonium with her husband, Pierre Curie. This lead to the radiation therapy, which is a therapy used for treating diseased cancer cells by putting radiation on the cancer cell.
What did Marie Curie invent first?
Madam Curie did not invent any elements. Hydrogen, Helium, and Lithium were produced in the Big Bang. Other natural elements were created when stars exploded. As cyclotrons had not been invented before her death, she could not have created or invented any elements. She discovered Radium however.
Identify the contributions of the three scientist who discovered the first radioactive elements?
H. Becquerel discovered that uranium was radioactive, i.e. was emitting energy which was unknown at the time. Marie Curie and Pierre Curie did further work on radioactivity and discovered new elements, radium and polonium which were also radioactive. Ernest Rutherford and his collaborator Soddy explored radioactivity systematically and discovered several new radioactive elements. More importantly they systematically developed procedures and concepts for defining radioactivity, such as radioactive half-life, activity versus time plots to better understand the energy emitted by radioactive elements: alpha particles (positive charge, mass of helium), beta particles (negatively charged particles or high energy electrons) and finally high energy electromagnetic radiation or gamma rays as they called it.
