Which scientist discovered the radioactive element radium?

  By GK Planet Team       Sunday, 24 December 2017
Q. Which scientist discovered the radioactive element radium?

A. Isaac Newton
B. Albert Einstein
C. Benjamin Franklin
D. Marie Curie

Answer: Marie Curie

Marie Skłodowska Curie (7 November 1867 – 4 July 1934) was a Polish and naturalized-French physicist and chemist who conducted pioneering research on radioactivity. She was the first woman to win a Nobel Prize, the first person and only woman to win twice, the only person to win a Nobel Prize in two different sciences, and was part of the Curie family legacy of five Nobel Prizes. She was also the first woman to become a professor at the University of Paris, and in 1995 became the first woman to be entombed on her own merits in the Panthéon in Paris.

Her achievements included the development of the theory of radioactivity, techniques for isolating radioactive isotopes, and the discovery of two elements, polonium and radium. Under her direction, the world's first studies into the treatment of neoplasms were conducted using radioactive isotopes. She founded the Curie Institutes in Paris and in Warsaw, which remain major centers of medical research today. During World War I, she developed mobile radiography units to provide X-ray services to field hospitals.
Marie Curie became the first woman to be awarded the Nobel prize and the first person to obtain two nobel prizes when she won the prize for the discovery of Polonium and Radium in 1911. Though it was Henri Becquerel that discovered radioactivity, it was Marie Curie who coined the term.
