What is the family of the element Europium?

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.

Is europium a main group element?

Europium was isolated in 1901 and is named after the continent of Europe. Being a typical member of the lanthanide series, europium usually assumes the oxidation state +3, but the oxidation state +2 is also common….

Where is europium used?

Europium is excellent at absorbing neutrons, making it valuable in control rods for nuclear reactors. Europium-doped plastic has been used as a laser material. It is also used in making thin super-conducting alloys.

Is ytterbium toxic?

Ytterbium has no known biological role. It has low toxicity. In common with many lanthanide elements, ytterbium is found principally in the mineral monazite. It can be extracted by ion exchange and solvent extraction.

Is europium named after Europe?

The name derives from the continent of Europe. It was separated from the mineral samaria in magnesium- samarium nitrate by the French chemist Eugène-Anatole Demarçay in 1896. The discovery of europium is generally credited to Demarcay, who separated the rare earth in reasonably pure form in 1901.

Why are 16 groups called Chalcogens?

-Group-16 elements are also called chalcogens. They are called so because most of the copper ores have copper in the form of oxides and sulphides. They also contain small amounts of selenium and tellurium. So, group-16 elements are named chalcogens.

Why group 15 elements are called Pnictogens?

Group 15 elements are also known as pnictogens because in Greek pigeon means to cholk or stifle. In the absence of the oxygen, molecular nitrogen has this property. That’s why group 15 elements are known as either nitrogen family or pnictogens.

Is calcium a element?

Calcium is a chemical element with symbol Ca and atomic number 20. Classified as an alkaline earth metal, Calcium is a solid at room temperature.

Is europium (Eu) heavy or light rare earth elements?

The Company uses classification nomenclature which considers heavy rare earths comprising europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), ytterbium (Yb), lutetium (Lu) and yttrium (Y). Light rare earths comprise lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd) and samarium (Sm).

What is the origin name for europium?

The new element was not one, but two elements. Demarcay gave the original name of samarium to one, and the other he called europium, after the continent of Europe. More than a century earlier, a heavy new mineral had been found near the town of Bastnas, Sweden, and given the name cerite.

Where can europium be found?

Although europium is not found in a pure form in nature, it can be found in an assortment of minerals; China and the United States are two major sources of the world’s europium, in the form of minerals which must be treated to extract europium and other elements. The element does not have a wide array of uses,…
