Discovery:
In 1787, Carl Arrhenius found a black mineral in a feldspar/quartz mine close to Ytterby, Sweden. He called it Ytterbite after the Ytterby. After Bengt Geijer and Johan Gadolin inspected the element, they found that it contained different elements along with a new rare earth metal. Ander Ekeberg confirmed Gadolin's findings and suggested to name the new metal Yttrium. However, Gadolin and Ekeberg's anaylses were incorrect and the identified substance was in fact the oxide of Beryllium. Beryllium was discovered a year later and Ytterbite was renamed as Gadolinite. Yttrium was the first rare-earth element to be discovered because Gadolin's yttria was mixed with eight other rare earth metals. Pure Yttrium metal was finally found in the year of 1828, in Berlin, by Friedrich Wöhler.

Uses:
As mentioned before, Yttrium has a great impact on our lives. Along with being used frequently in alloys, it is also produces the red phosphor in color television tubes. Isotope 90Y is used in treatments for some cancers, and in some needles to cut off nerves that transmit pain in the spinal cord. Yttrium iron garnets are used as microwave filters. It blocks some frequencies while collecting others through satellites or another communication device.
