Demarçay in 1901 in Paris, France. The most reactive member of the lanthanide group of elements and one of the less abundant (2.1 ppm in the Earth's crust), europium is a ductile silvery metal which reacts rapidly with air and water. As a result of its reactive nature, the metal has limited applications, but some is used in the manufacture of thin-film superconductor alloys. Europium is also used as control rod material in nuclear reactors due to its ability to absorb neutrons.
