Yttrium was discovered in 1794 by Johann Gadolin. Yttrium was named after the name of the Swedish town "Ytterby".
Yttrium's melting point is at 1523.0 C (1796.15 K, 2773.4 F) and its boiling point is at 3337.0 C (3610.15 K, 6038.6 F).
Yttrium is a soft silver highly crystalline metal.
Yttrium has only one naturally occurring stable isotope, 89-Y.
Elemental yttrium was first isolated in 1828 by Friedrich Wohler.
Yttrium is used in the production of phosphors, CRT and LED displays, electrodes, electrolytes, electronic fibers, lasers, superconductors, many medical applications, etc.
There is no known biological role and exposure to yttrium compounds can cause lung disease, including cancer.
Yttrium, in its pure state (and in bulk form), is stable in air, due to formation of an oxide layer on its surface. However, under certain circumstances it can be very reactive in air.
Yttrium's chemical properties are very similar to those of lanthanides and it is always found in nature together with lanthanides in Rare Earth minerals. This fact makes Yttrium to be very often classified as Rare Earth metal.
Yttrium is never found freely in nature.
Yttrium is the 28th most abundant element in Earth's crust.
Yttrium is form in red giant stars and in supernovas.
Yttrium isotopes are very common products of the nuclear fusion of uranium.
Yttrium is extracted from Yttrium Oxide.
Over 7000 tones of Yttrium Oxide were produced in 2013 which produce a few tones of Yttrium metal.
