Europium is a chemical element; it has symbol Eu and atomic number 63. It is a silvery-white metal of the lanthanide series that reacts readily with air to form a dark oxide coating. Europium is the most chemically reactive, least dense, and softest of …

europium (Eu), chemical element, a rare-earth metal of the lanthanide series of the periodic table. Europium is the least dense, the softest, and the most volatile member of the lanthanide series.

Europium is used in the printing of euro banknotes. It glows red under UV light, and forgeries can be detected by the lack of this red glow. Low-energy light bulbs contain a little europium to give a more natural light, by balancing the blue (cold) light with a little red (warm) light.

2018年6月27日 · Europium has a bright, shiny surface. It is steel gray and has a melting point of 826 ° C (1,520 ° F) and a boiling point of about 1,489 ° C (2,712 ° F). The density is 5.24 grams per cubic centimeter. Europium has a strong tendency to absorb neutrons, making it useful in nuclear power production.

2013年7月16日 · Europium, a member of the lanthanides group of elements, ignites at air temperatures of 302 to 356 F (150 to 180 C), which is the case of all other rare earth metals with the exception of...

Europium is a chemical element with symbol Eu and atomic number 63. Classified as a lanthanide, Europium is a solid at room temperature. [Xe]6s 2 4f 7. J.C. Slater, J Chem Phys, 1964, 41 (10), 3199-3205. DOI:10.1063/1.1725697.

Europium is a soft, silvery metal and the most reactive of the rare earth metals, reacting quickly with oxygen and water. It ignites spontaneously when heated to ca 180ºC. Europium has two natural isotopes: 151 Eu, which is now known to be radioactive; and 153 Eu. Only registered users can comment on this article. Seeing red? That'll be europium.
