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.
Origin / Meaning of the name Gadolinium
Gadolinium is named after
the Finnish chemist and geologist Johan Gadolin
Classification of the Gadolinium Element
Gadolinium
classified as an element in the Lanthanide series as one of 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.
