It is the most reactive metal, quickly oxidizing in air and seem like calcium in its reaction with water. ... Europium is now prepared by mixing Eu 2 O 3 with a 10%-excess of lanthanum metal and heating the mixture in a tantalum crucible under high vacuum. Being a lanthanide element, it usually exhibits +3 oxidation state but its +2 oxidation state is also not uncommon. Its atomic number is 63 and is represented by the symbol Eu. It will ignite in air about 150° C to 180° C. It is hard as lead and very ductile. Europium chloride (EuCl 3) Europium iodide (EuI 3) Europium oxide (Eu 2 O 3) Interesting facts: It is the most reactive of all the rare earth elements. With atomic number 63, it inhabits the bar of elements that squeeze numerically between barium and hafnium. It is used in nuclear reactors control rods. It is obtained from many minerals like: bastnasite (family of three carbonate fluoride mineral), monazite (reddish brown phosphate mineral), xenotime (phosphate mineral) and loparite-(Ce) (granular brittle oxide mineral). Europium was discovered by Eugène-Anatole Demarçay (FR) in 1896. Discovered in Europe, led us to illustrate the map of Europe. Both of its naturally occurring isotopes are stable: europium-151 (47.81 percent) and europium-153 (52.19 percent). It is the most reactive of the rare-earth metals, quickly oxidizing in air. Europium was isolated in 1901 and is named after the continent of Europe. Get periodic table facts on the chemical and physical properties of the element element europium, which it atomic number 63.

Element 63 of Periodic table is Europium with atomic number 63, atomic weight 151.964. World Of Chemicals, Eugene-Anatole Demarcay — Discoverer Of Europium Element. Europium is also used in quantum memory chips which can store data for days at a time. It is the most reactive of the lanthanide group: it tarnishes quickly in air at room temperature, burns at about 150 C to 180 C and reacts readly with water. Encyclopedia.com, Europium. William Crookes, July 21, 1905. It resembles calcium in its reaction with water. The smartphone you may be using right now to look at this unique Periodic Table is made up of some 30 elements – over half of which may give cause for concern in the years to come because of increasing scarcity. One of the least abundant rare earths (its concentration in Earth’s crust is nearly the same as bromine’s), it occurs in minute amounts in many rare-earth minerals such as monazite and bastnasite and also in the products of nuclear fission. The three group 4 elements that occur naturally are titanium, zirconium, and hafnium. Europium is a soft silvery metal, hard as lead and is quit ductile. Its minerals deposits are found in China. Group 4 is a group of elements in the periodic table.It contains the elements titanium (Ti), zirconium (Zr), hafnium (Hf) and rutherfordium (Rf).
