Facts about the
Definition of the Element Praseodymium
The Element Praseodymium is defined as...
A soft, silvery, malleable, ductile rare-earth element that
develops a characteristic green tarnish in air. 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.
Interesting Facts
about the Origin and Meaning of the element name Praseodymium
What are the origins of the word Praseodymium ?
The name originates from the Greek words 'prasios' meaning green
and 'didymos' meaning twin.
Facts about the
Classification of the Element Praseodymium
Praseodymium 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 Argon - 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 Praseodymium 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. Praseodymium was discovered by the Austrian chemist Baron
Aver von Welsbach in 1885. 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
Praseodymium is
just one element that can be found.
