n. 铕

铕

europium
n 1: a bivalent and trivalent metallic element of the rare earth
group [synonym: {europium}, {Eu}, {atomic number 63}]

Europium \Eu*ro"pi*um\, n. [NL.; Europe -ium, as in
aluminium.] (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.

  • Magnetism of europium under extreme pressures
    MAGNETISM OF EUROPIUM UNDER EXTREME PRESSURES model may account for the pressure-induced loss of magnetic order and emergence of superconductivity in trivalent Ce [13], an element sporting only a single 4f electron, the full screening of seven 4f electrons on each Eu ion by two conduction electrons (per Eu atom) would seem highly unlikely
  • What Is It - HPS Chapters
    Europium is a silvery-white metal It is the softest, least dense, and most volatile member of the lanthanide series, and it ignites in air at high temperatures (150 to 180°C) In nature, europium occurs as two stable isotopes (Isotopes are different forms of an element that have the same number of protons in the nucleus but a different number of neutrons ) Europium-153 accounts for 52% of
