Interesting Facts about the Origin and Meaning of the element name Promethium
What are the origins of the word Promethium ?
The name originates from Prometheus from Greek mythology, who stole the fire of the sky and gave it to mankind.
Facts about the Classification of the Element Promethium
Promethium 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 Promethium - 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 Promethium 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. Promethium was discovered by Jacob A. Marinsky, Lawrence E. Glendenin and Charles D. Coryell in 1946. 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 Promethium is just one element that can be found.
