Europium
Europium is the most reactive rare-earth element. Because of its high reactivity, solid europium rarely looks shiny. It reacts with water to form europium hydroxide (Eu(OH) 3). It swiftly oxidizes in air, ignites in the range of 150–180°C to form Eu 3+ oxide (Eu 2 O 3). It dissolves in most of the acidic and basic solvents.
About Rare Earths | Shin-Etsu Rare Earth
Rare earth is a general term for 17 elements, including 15 elements (lanthanoid*1) with atomic numbers 57 to 71 in the Periodic Table plus scandium (Sc) with 21 and yttrium (Y) with 39. Rare earth was discovered in Sweden in 1794 and was called "rare" (earth) because it was considered to be an extremely rare substance at that time.
Europium (Eu) Element: Reactions, Properties, Uses, Effects
Europium has an atomic number of 63 and is a silvery-white rare earth metal. It has a melting point of 826°C (1520°F) and a boiling point of 1489°C (2712°F). Eu has a solid phase density of 5.244 g/cm 3 and a liquid or molten phase density of 5.13 g/cm 3. It is malleable which means it can be easily beaten into thin sheets without any cleavage.
