Eighth most abundant 'rare earth' found in the earth's crust (5.0 ppm). Scandium metal is used in some aerospace applications. Scandum oxide (Sc2O3) is used in the manufacture of high-intensity electric lamps. Scandium iodide (ScI3) is used in lamps that produce light having a color closely matching natural sunlight. Occurs mainly in the minerals thortveitile (~34% scandium) and wiikite. Also in some tin and tungsten ores. Pure scandium is obtained as a by-product of uranium refining. yFuD2JSDueU Scandium

Oganesson was identified in 2002 by a team composed of Russian scientists at Joint Institute for Nuclear Research, Dubna and American scientists at the Lawrence Livermore National Laboratory.

It was produced by the bombardment of californium with calcium.

Ununoctium was the temporary IUPAC systematic element name. Named after the Russian nuclear physicist Yuri Oganessian 21 1879 Lars Fredrik Nilson Sweden From the Latin word "Scandia" meaning "Scandinavia"

Oganesson is harmful due to its radioactivity

Oganesson is historically known as eka-radon

Oganesson is used for scientific research purposes only.
