Facts about the
Definition of the Element Terbium
The Element Terbium is defined as...
A soft, silvery-gray metallic rare-earth element, used in x-ray
and color television tubes.
Interesting Facts
about the Origin and Meaning of the element name Terbium
What are the origins of the word Terbium ?
The name originates from the work of Carl Gustaf Mosander. Carl
Gustaf Mosander was able to separate gadolinite into three
materials, which he named yttria, erbia and terbia - a combination
of these names results in Terbium.
Facts about the
Classification of the Element Terbium
Terbium 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 Terbium 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. Terbium was discovered by Carl Gustaf Mosander in Sweden in
1843. 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
Terbium is
just one element that can be found.
