What is the element Praseodymium as on the Periodic Table?

Definition of the Praseodymium Element
A soft, silvery, malleable, ductile rare-earth element that develops a characteristic green tarnish in air. It is more resistant to corrosion in air the other rare metals, but it still needs to be stored under oil or coated with plastic. It occurs naturally with other rare earths in monazite and is used to color glass and ceramics yellow, as a core material for
Carbon arcs, and in metallic alloys. The Atomic Number of this element is 59 and the Element Symbol is Pr.

Origin / Meaning of the name Praseodymium
The name originates from the Greek words 'prasios' meaning green and 'didymos' meaning twin.

 

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

Facts about the Discovery and History of the Praseodymium Element
Praseodymium was discovered by the Austrian chemist Baron Aver von Welsbach in 1885

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