WordNet
  1. (n) europium
    a bivalent and trivalent metallic element of the rare earth group
Webster's Revised Unabridged Dictionary
  1. Europium
    (Chem) A metallic element of the rare-earth group (Lanthanide series), discovered spectroscopically by Demarcay in 1896. Symbol, Eu; atomic number 63; at. wt., 151.965 (C=12.011); valence = +2 or +3.
Century Dictionary and Cyclopedia
  1. (n) europium
    A supposed new element announced by Demarçay in 1901, obtained in very small quantity as oxid, sulphate, etc., from samar-skite and monazite. Its compounds have been further examined by Urbain and Lacombe. It is characterized by a special spark-spectrum, and also by a phosphorescent spectrum, and appears to be intermediate between samarium and gadolinium, with an atomic weight of about 151.79.
Etymology

Instead, they hope to strike neodymium, europium and other exotic-sounding rare earth metals -- a group of 15 elements, plus two others with similar properties, used in clean-energy technology, military hardware and cell phones. hcn.org

Usage in scientific papers

We present results for the chemical evolution of the Milky Way including predictions for elements from Deuterium to Europium. A comparison with the most accurate and recent data allows us to draw important conclusions on stellar nucleosynthesis processes as well as on mechanisms of galaxy formation.

Experimental Quantum Computation with Nuclear Spins in Liquid Solution

Roederer derived isotopic fractions of europium, samarium and neodymium in two metal-poor giants with apparently different nucleosynthetic histories, extending the examination of the neutron-capture origin of multiple rareearth elements in metal poor stars to the isotopic level for the first time.
