What is the element Lutetium as on the Periodic Table?


Periodic Table Group and Classification of the of the Lutetium Element
Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. Lutetium is 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. Nearly 75% of all the elements in the Periodic Table are classified as metals which are detailed in the List of Metals.

 

Definition of the Lutetium Element
A silvery-white rare-earth element that is exceptionally difficult to separate from the other rare-earth elements, used in nuclear technology. It is the hardest and the densest of the lanthanides. The Atomic Number of this element is 71 and the Element Symbol is Lu.

Origin / Meaning of the name Lutetium
The name originates from the Latin word Lutetia from the ancient Latin name for the city of  Paris.

Facts about the Discovery and History of the Lutetium Element
Lutetium was discovered by by French scientist Georges Urbain and Austrian mineralogist Baron Carol Auer von Welsbach in 1907.

What is Lutetium - 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 and now recognises more periods and elements than Dimitri  Mendeleev knew in his day 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.
