Facts about the
Definition of the Element Lutetium
The Element Lutetium is defined as...
A silvery-white rare-earth element that is exceptionally difficult
to separate from the other rare-earth elements, used in nuclear
technology.
Interesting Facts
about the Origin and Meaning of the element name Lutetium
What are the origins of the word Lutetium ?
The name originates from the Latin word Lutetia meaning Paris.
Facts about the
Classification of the Element Lutetium
Lutetium classified as an element in the Lanthanide series as one
of the "Rare Earth Elements" which can located in Group 3 elements
of the Periodic Table and in the 6th and 7th periods. The Rare
Earth Elements are divided into the Lanthanide and Actinide
series. The elements in the Lanthanide series closely resemble
lanthanum, and one another, in their chemical and physical
properties. Their compounds are used as catalysts in the
production of petroleum and synthetic products.

Facts and Info about
the element Argon - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the
International Union of Pure Applied Chemistry, IUPAC, in 1985
which includes the Lutetium element. The famous Russian Scientist,
Dimitri Mendeleev, perceived the correct classification method of
"the periodic table" for the 65 elements which were known in his
time. Lutetium was discovered by by French scientist Georges
Urbain and Austrian mineralogist Baron Carol Auer von Welsbach in
1907. The Standardised Periodic Table now recognises more periods
and elements than Dimitri Mendeleev knew in his day but still all
fitting into his concept of the "Periodic Table" in which
Lutetium is
just one element that can be found.
