The Full Story
Francium was first identified in 1939 by French physicist Marguerite Perey at the Curie Institute in Paris. She discovered it as a decay product of actinium, making it a highly radioactive and extremely rare element. Francium is the heaviest known alkali metal and is too scarce for practical collection in meaningful quantities. Perey’s discovery was a landmark for both nuclear chemistry and women in science.
