Marie Curie was born in Warsaw, Poland on November 7 1867 and passed away on July 4 1934. She was a french physicist and chemist. (Edgar Fahs Smith Collection, 1898)
She predicted that radiation comes from inside of the atom but not from the interaction between molecules. she thought the rays were not dependent on the uranium's form, but on its atomic structure.
Marie discovered polonium, and then radium salts weighing about 0.1 gram that took 4 years to be processed from several tons of uranium ore. They discovered not only polonium, but also radium, through their work with pitchblende.
Their research helped shape the understanding or radioactive atoms and their properties. She created new treatment of diseases such as chemo. She used radium to advance x-ray quality and she treated over 1 million soldiers in World War I in 1914,
the red and blue circle is the nucleus, the squiggly line is the gamma radiation, and the two protons and neutrons are the alpha radiation.
Marie won the Nobel Prize in Physics in 1903 and in Chemistry in 1911 and she was the first woman to win the award. Marie discovered the elements radium and polonium which she named after where she was born, Poland and she created the word radioactive
