Description and uses
Lutetium is the 71st element of the periodic table. It was discovered in 1907 by Georges Urbain when he extracted it
from yttrium oxide, which contains many of the lanthanides.
Lutetium has two naturally occurring isotopes. 175Lu is by far the most abundant, with an abundance of
around 97.4%. 176Lu radioactive, and is less abundant, with an abundance of around 97.4% and a half-life of 3.8x1010 years.
