Facts about the
Definition of the Element Chromium
The Element Chromium is defined as...
A lustrous, hard, steel-gray metallic element, resistant to
tarnish and corrosion and found primarily in chromite. It is used
in the hardening of steel alloys and the production of stainless
steels, in corrosion-resistant decorative platings, and as a
pigment in glass. The most common uses of Chromium are
in Dyes and paints, Stainless steel, Metallurgy, Chrome plating,
Green rouge metal polish and Magnetic tape.
Interesting Facts
about the Origin and Meaning of the element name Chromium
What are the origins of the word Chromium ?
The name originates from the Greek word chroma meaning color
Facts about the
Classification of the Element Chromium
Chromium is classified as a "Transition Metal" which are located
in Groups 3 - 12 of the Periodic Table. An Element classified as a
Transition Metals is ductile, malleable, and able to conduct
electricity and heat.
Brief Facts about the
Discovery and History of the Element Chromium
Chromium was discovered by Louis Vauquelin in 1797 who was also
able to detect traces of chromium in precious gems, such as ruby
and emerald. A lead chromate named as Siberian Red Lead was found
by Johann Gottlob Lehmann in 1761. Peter Simon Pallas found that
the Siberian Red Lead mineral that had very useful properties as a
pigment in paints.

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 Chromium 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. Chromium was discovered by Louis Vauquelin in 1797 who was
also able to detect traces of chromium in precious gems, such as
ruby and emerald. A lead chromate named as Siberian Red Lead was
found by Johann Gottlob Lehmann in 1761. Peter Simon Pallas found
that the Siberian Red Lead mineral that had very useful properties
as a pigment in paints. 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
Chromium is
just one element that can be found.
