In thisarticle, we will be looking at the discovery and the early history of theseelements through the following 7 points.1. The periodic table was not always in theposition in which we see it today, as more elements were discovered they wereadded accordingly. The first time scientists came across the idea of rareelements was after the discovery of ytterbite, which was later renamed asgadolinite.2. Ytterbite was then sent off to the Universityof Turku for an in depth examination. There, the professor after processing theelement through different procedures was able to extract an oxide but was notable to place a specific identity to it. Also, no other elements were separatedthat are used to form the rare element in combination.3. Later in 1803, a couple of scientists in anindependent study discovered a white oxide, which they named as ceria. At thesame time, another scientist named Martin Klaproth discovered the same elementand gave it a different name, ochroia.4. By this time, people were familiarized withthe idea of rare elements. However, for nearly thirty years no other rareelements were discovered by scientists.5. Later, more rare elements were found, from thesame layers of the crust from which the first two rare elements had beendiscovered.6. In the same period of scientific history, thefamous Lanthana surfaced. This discovery was credited to Carl Mosander whoseparated ceria through heating the nitrate and then dissolving the resultingproduct in nitric acid. This process produced a raw form of Lanthana. It wasntfor another three years after that time until pure Lanthana and didymia, bothversions of the rare earth element, were discovered.7. From here on forward, the discovery of rareelements picked up speed. A number of rare earth elements were discovered. Itwas by 1842 that the majority of the minerals were known to the people workingin the field. At first this element was used for pure scientific reasons only,mostly for research in universities. However, with time, scientists discovereda number of other beneficial uses for these elements. They covered a huge base,from being used in making different parts in the aviation machinery industry tobeing used in a number of medical treatments that benefit humans. One exampleis the use of Lanthana in medicine for the renal failure.
