Marie Curie Impresses All
By: Sydney Rouah
On November 7, 1867 Maria Skodowska was born in Warsaw, Poland. Maria was the youngest child of five siblings. Both her mother and father were teachers. In Maria's younger ages she took after her father, Ladislas. He was a Math and science instructor. Sadly at the age of only eleven Maria's mother, Bronsitwa, had died of tuberculosis.
A top graduate in her secondary school, she couldn't appear as a student in the men-only university of Warsaw. Of course she didn't let that stop her. Maria moved to Paris to study at the Sourbourne. There she met and married Pierre Curie. Together they worked on many discoveries and research projects. Later they had two girls Irene in 1897 and Eve in 1904
Curie discovered that there are things in atoms called sub atomic particles. This made a huge difference on how we think about science. The rays that come out of uranium come from directly in the atoms. It explains the actions of uranium.
She formed the idea for these discoveries by studying another man's work. His name was Henri Becquerel. He discovered that rays come out of uranium. Curie confirmed that the rays remained the same no matter if the uranium was dry, wet, dirty, or dull. Curie made the word radioactivity. It describes the rays that come out of the minerals such as uranium or radium. Curie took Becquerel's work even further when she confirmed that the rays came from uranium's atomic structure.
Curie discovered radium and polonium , two elements. She named polonium after her native country, Poland. She also developed methods for radium extraction which is taking out pure radium salts and metal. Curie also used medical radiation to treat soldier's injuries during World War One Curie won the Nobel Prize for her amazing discoveries. Curie also was the first woman to win a Nobel Prize, and the first person to win in more than one sciences.
What Her Discoveries Look Like
Radium when fresh is a brilliant white. When exposed to air it blackens. Finally when exposed to a flame it turns red. For uranium it depends what form of uranium. Pure uranium is silvery gray. Unlike radium, uranium doesn't glow
