• Europium - Wikipedia

    en.wikipedia.org/wiki/Europium Europium is a chemical element with the symbol Eu and atomic number 63. Europium is the most reactive lanthanide by far, having to be stored under an inert fluid to protect it from atmospheric oxygen or moisture. Europium is also the softest lanthanide, as it can be dented with a fingernail and easily cut with a knife.

    www.rsc.org/periodic-table/element/63/Europium Europium’s story is part of the complex history of the rare earths, aka lanthanoids. It began with cerium which was discovered in 1803. In 1839 Carl Mosander separated two other elements from it: lanthanum and one he called didymium which turned out to be a mixture of two rare earths, praseodymium and neodymium, as revealed by Karl Auer in 1879.

    en.wikipedia.org/wiki/Isotopes_of_europium Naturally occurring europium (63 Eu) is composed of 2 isotopes, 151 Eu and 153 Eu, with 153 Eu being the most abundant (52.2% natural abundance).While 153 Eu is observationally stable, 151 Eu was found in 2007 to be unstable and undergo alpha decay. The half-life is measured to be (4.62 ± 0.95(stat.) ± 0.68(syst.)) × 10 18 y which corresponds to 1 alpha decay per two minutes in every ...
