Facts about the Definition of the Element Lanthanum
The Element Lanthanum is defined as...
A soft, silvery-white, malleable, ductile, metallic rare-earth element, obtained chiefly from monazite and bastnaesite and used in glass manufacture and with other rare earths in carbon lights for movie and television studio lighting.
Interesting Facts about the Origin and Meaning of the element name Lanthanum
What are the origins of the word Lanthanum ?
The name originates from the Greek word lanthanein meaning 'to lie hidden'.
Facts about the Classification of the Element Lanthanum
Lanthanum 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 Lanthanum - 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 Lanthanum 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. Lanthanum was discovered by Carl G. Mosander in 1839. 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 Lanthanum is just one element that can be found.
