Facts about the
Definition of the Element Cobalt
The Element Cobalt is defined as...
A hard, brittle metallic element, found associated with nickel,
silver, lead, copper, and iron ores and resembling nickel and iron
in appearance. It is used chiefly for magnetic alloys,
high-temperature alloys, and in the form of its salts for blue
glass and ceramic pigments. The most common uses of Cobalt are
in Magnets, Ceramics, Magnetic alloys, Cobalt boats, Glassware,
Catalysts for the petroleum and chemical industries, Steel-belted
radial tires and it is also used in radiotherapy
Interesting Facts
about the Origin and Meaning of the element name Cobalt
What are the origins of the word Cobalt ?
The name cobalt comes from the German word kobalt , meaning evil
spirit, the metal being so called by miners because it was
poisonous.
Facts about the
Classification of the Element Cobalt
Cobalt 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.

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 Cobalt 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. Cobalt was discovered by George Brandt (1694-1768) in 1737. 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
Cobalt is
just one element that can be found.
