Europium is a chemical element that belongs to the Lanthanide series. This means it is a rare-earth element. It is distinct for being the most reactive, the rarest, the least dense, and the softest rare-earth element. It is so reactive that it is stored beneath a non-reactive fluid. Europium is named after Europe. Paul-Émile Lecoq...Continue Reading

Introduction Erbium is one of the 17 rare-earth elements. This means it also belongs to the lanthanide series. Its atomic number is 68, and its symbol is Er. When one is told that Erbium is a rare-earth metal, one might expect it to be challenging to come across. However, Erbium ranks number 45 in the...Continue Reading

Dysprosium is a rare-earth element with a lustrous and silvery appearance. Like most other rare-earth metals, it belongs to the Lanthanide series. Its name was derived from the Greek word dysprositos which can be translated as hard to get. Dysprosium was discovered in 1886 by a scientist known as Paul Emile Lecoq de Boisbaudran. However,...Continue Reading

If there is a metal that is ignored by us, I think that is scandium. Scandium is found in most rare earth elements and uranium deposits, but it can only be extracted from a few mines around the world. Due to the low availability and difficulty in preparation, which was succeeded in 1937, of scandium,...Continue Reading

Rare-earth element is a general term for 17 elements of lanthanides as well as scandium and yttrium in the chemical periodic table. Scandium and yttrium are included in rare earth element because they are often symbiotic with lanthanide elements in mineral deposits, and thus have similar chemical properties. Rare earth materials are important for many...Continue Reading
