Acerca de Europio

The most reactive of the rare earth elements, europium (Eu) must be stored away from air and moisture to prevent rapid oxidation. Element 63 belongs to the lanthanide series in period 6 of the f-block, with an atomic mass of 151.96, the electron configuration [Xe] 4f⁷ 6s², and a Pauling electronegativity of 1.2. Europium is best known for its luminescence: its compounds provide the red and blue phosphors in television and computer displays, and they form part of the anti-counterfeiting fluorescence built into euro banknotes. A soft metal, it readily adopts the +2 oxidation state alongside the more usual +3.
