Facts about the
Definition of the Element Barium
The Element Barium is defined as...
A soft, silvery-white alkaline-earth metal, used to deoxidize
copper and in various alloys.
Interesting Facts
about the Origin and Meaning of the element name Barium
What are the origins of the word Barium ?
The name originates from the Greek word 'barys' meaning heavy. The
oxide was at first called barote, by Guyton de Morveau, which was
changed by Antoine Lavoisier to baryta, which was modified to
"barium".
Facts about the
Classification of the Element Barium
Barium is classified as an "Alkaline Earth Metals" which are
located in Group 2 elements of the Periodic Table. An Element
classified as an Alkaline Earth Metals are found in the Earth’s
crust, but not in the elemental form as they are so reactive.
Instead, they are widely distributed in rock structures.

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 Barium 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. 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
Barium is
just one element that can be found.
