It is characterized as a metal and is usually found in a +3 and +2 oxidation state. Europium is mostly always combined with … Its atomic number is 63 and its atomic mass is 151.964. Monazite contains all of the rare earth elements, often in concentrations of up to 50%. Europium has a strong tendency to absorb neutrons, making it useful in nuclear power production. Most of the minerals comprise of europium with the vital sources being monazite and bastnasite. Europium was found in 1901 and it is named after Europe. In the case of Europium the period number is 6. PLEASE no answers telling me to "google it" because don't you think I'd have tried that?! But for europium, many historians play events the other way round, ignoring europium's Fleming, William Crookes. Europium is a metallic element discovered in 1901 in Paris by the French scientist Eugène-Anatole Demarcay. Rare earth elements were discovered in 1787 by Swedish Army Lieutenant Carl Axel. Europium is used in the form of its salts as coatings for cathode ray tubes and in the form of its organic derivatives as shift reagents in NMR spectroscopy. Europium was found in much higher concentrations than expected in samples of rock brought back from the Moon. The nature of the europium anomaly found is used to help reconstruct the relationships within a … Europium has 2 naturally occurring isotopes: europium-151 and europium-153. It is a soft white-silvery metal. There are many minerals that contain europium, the important of these are bastnasite and monazite. It can be found in minute quantities in most rocks, soils and waters (normally < 5 ppm), but the real challenge is to find it in high enough concentrations to make it economically feasible to mine. Valence number: 2 valence electrons; Where is it found: Europium isn't found as a free element but it is found in other elements about 1,600°C;; sp.
