How did Marie Curie discovered polonium?
Polonium was discovered by Marie Sklodowska Curie, a Polish chemist, in 1898. She obtained polonium from pitchblende, a material that contains uranium, after noticing that unrefined pitchblende was more radioactive than the uranium that was separated from it.
How did Marie Curie discover radiation?
The Curies extracted uranium from ore and to their surprise, found that the leftover ore showed more activity than the pure uranium. They concluded that the ore contained other radioactive elements. This led to the discoveries of the elements polonium and radium.
How did Marie Curie discover radium and polonium for kids?
Through her research on uranium, Marie went on to discover two new chemical elements. These were Polonium (named after her home country Poland) and Radium (named after radiation). Marie and Pierre did not have a laboratory and so did many of their experiments in a converted shed.
What did Marie Curie found out about uranium compound?
When she realized that some uranium and/or thorium compounds had stronger radiation than uranium, she made the following hypothesis: there must be an unknown element in the compound which had a stronger radiation than uranium or thorium.
What is Marie Curie’s full name?

What did Marie Curie discover?
Marie Curie discovered two new chemical elements – radium and polonium. She carried out the first research into the treatment of tumors with radiation, and she founded of the Curie Institutes, which are important medical research centers.
What were Marie Curie’s discoveries?
Marie and Pierre Curie were scientists who in 1898 discovered the elements radium and polonium. They studied radioactivity and for their work they received the Nobel Prize for physics in 1903. Marie Curie discovered the radioactive element Radium by processing a ton of mineral known as pitchblende.
