Strontium was recognized as a new element in 1790 when Adair Crawford analyzed a mineral sample from a lead mine near Strontian, Scotland. Until then scientists had thought strontium and barium were the same element, and only bariumâs existence had been recognized. The mineral took its name from the Scottish town and was called strontianite (strontium carbonate).
The 1789 discovery of uranium in the mineral pitchblende is credited to Martin Heinrich Klaproth, who named the new element after the planet Uranus. EugÃ¨ne-Melchior PÃ©ligot was the first person to isolate the metal and its radioactive properties were discovered in 1896 by Henri Becquerel.
