EXTRA, EXTRA, READ ALL ABOUT MARIE CURIE!

By: Devyn Robinson

WHY SHE IS FAMOUS!

Marie Curie was a physicist and chemist best known for her work in radioactivity, techniques for isolating radioactive isotopes (variants of a particular chemical element, that vary from each other in the number neutrons that they have), along with discovery of the elements of poloium and radium. She was rewarded two Nobel Prizes - one in physics and another in chemistry. She was the first person to win two Nobel Prizes. She won them in the year of 1903.

HER EARLY LIFE!She was a top student in her secondary school. Curie could not attend the Men-Only University of Warsaw. She instead continued her education in Warsaw's "Floating University", a set of underground informal classes held in secret. She graduated in the year of 1883.

HOW SHE GOT THE IDEA!

Henry Bequerel (a scientist that she worked with) had already discovered radioactivity from uranium in the year of 1896. The Curies became inspired by his discovery and used an electrometer which Marie Curie's husband, Pierre Curie, had invented. This electrometer reacted to the ionisation (the process of converting an atom or molecule into an ion) in the air, which produced radioactivity. This enabled her to know that radioactivity came from the atoms of the substance, not a chemical reaction.After her husbands sudden death, Marie Curie went on ahead to discover pure radium metal.      

HER INVENTION!

Marie Curie revolutionized radioactivity by sheer hard work and determination.  Henry Becquerel came up with great findings of radioactivity and during that time a hot debate was all over the property of radioactivity.  Though Marie Curie researched the same subject she found that there are other elements that supported radioactivity.  Through her research, she found that radiation can kill human cells, and can be used to treat cancer to destroy the tumor cells. She coined the word radioactivity, and gave the idea of X-ray machines, a great value to mankind.
