Question

Who discovered Radium ?

Answer 1

Radium (Latin radius, ray) was discovered by Marie Skłodowska-Curie and her husband Pierre in 1898 in pitchblende from North Bohemia, in the Czech Republic (area around Jáchymov). While studying pitchblende the Curies removed uranium from it and found that the remaining material was still radioactive. They then separated out a radioactive mixture consisting mostly of barium which gave a brilliant green flame color and crimson carmine spectral lines which had never been documented before. The Curies announced their discovery to the French Academy of Sciences on 26 December 1898.

In 1902, radium was isolated as a pure metal by Curie and André-Louis Debierne through the electrolysis of a pure radium chloride solution by using a mercury cathode and distilling in an atmosphere of hydrogen gas.

Answer 2

Marie and Pierre Curie, a husband and wife chemist couple.  She later died from a disease that was most likely the result of radiation exposure; the dangers of radiation exposure were not yet known.

Marie Curie is typically given primary credit, possibly because she is one of the few female scientists in history of any note.

Answer 3

Marie Curie (born Maria Skłodowska; also known as Maria Skłodowska-Curie; November 7, 1867 – July 4, 1934) was a physicist and chemist of Polish upbringing and, subsequently, French citizenship. She was a pioneer in the field of radioactivity, the first and only person honored with Nobel Prizes in two different sciences, and the first female professor at the University of Paris.

She was born in Warsaw, Vistulan Country, Russian Empire, and lived there until she was 24. In 1891 she followed her elder sister Bronisława to study in Paris, where she obtained her higher degrees and conducted her scientific work. She founded the Curie Institutes in Paris and Warsaw. She was the wife of fellow-Nobel-laureate Pierre Curie and the mother of a third Nobel laureate, Irène Joliot-Curie.

While an actively loyal French citizen, she never lost her sense of Polish identity. Madame Curie named the first new chemical element that she discovered (1898) "polonium" for her native country,[1] and in 1932 she founded a Radium Institute (now the Maria Skłodowska-Curie Institute of Oncology) in her home town, Warsaw, headed by her physician-sister Bronisława.
