Definition of the Gadolinium Element
A silvery-white, malleable, ductile, metallic rare-earth element obtained from monazite and bastnaesite and used in improving high-temperature characteristics of
Iron, Chromium, and related alloys. The metal does not tarnish in dry air but an oxide film forms in moist air. Gadolinium reacts slowly with water and dissolves in acids. The Atomic Number of this element is 64 and the Element Symbol is Gd.

Origin / Meaning of the name Gadolinium
Gadolinium is named after the Finnish chemist and geologist Johan Gadolin.

 

Periodic Table Group and Classification of the of the Gadolinium Element
Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. Gadolinium 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.

Facts about the Discovery and History of the Gadolinium Element
Gadolinium was discovered by Jean de Marignac in France in 1880.

What is Gadolinium - 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 Gadolinium is just one element that can be found.
