What are facts about europium?

Answer 1

Europium is not found in nature as a free element. Many minerals contain europium, with the most important sources being bastnäsite and monazite. Depletion or enrichment of europium in minerals relative to other rare earth elements is known as the europium anomaly.

Europium has also been identified in the spectra of the sun and certain stars.

Europium has no known biological role.

Divalent europium in small amounts is the activator of the bright blue fluorescence of some samples of the mineral fluorite (CaF2). The most outstanding examples of this originated aroundWeardale, and adjacent parts of northern England, and indeed it was this fluorite that gave its name to the phenomenon of fluorescence, although it was not until much later that europium was discovered or determined to be the cause.

Answer 2

Europium was found in 1901 and it is named after Europe. Its atomic number is 63 and its Atomic Mass is 151.964. It was found by Eugene Demacray and is found in bastinasite, monasite, xenotime, and loparite. It does not exist in a pure form and is a bit less radioactive than caesium and strontium.

Answer 3

Europium is used in color TVs. Europium-doped plastic is used as a laser material.
