Definition of the Cobalt Element
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.

Origin / Meaning of the name Cobalt
The name cobalt comes from the German word kobalt , meaning evil spirit, the metal being so called by miners because it was poisonous.

Classification of the Cobalt Element
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 about the History and the Discovery of the Cobalt Element
Cobalt was discovered by George Brandt (1694-1768) in 1737

Occurrence the Cobalt Element
Obtained from sulfur, arsenic, oxygen, cobaltine

Associated Uses of Cobalt

Cobalt and the Periodic Table
Check out Cobalt on the Periodic Table which arranges each chemical element according to its atomic number, as based on the periodic law, so that chemical elements with similar properties are in the same column. Our Periodic Table is simple to use - just click on the symbol for Cobalt for additional information and for an instant comparison of the Atomic Weight, Melting Point, Boiling Point and Mass - G/cc with any other element. An invaluable source of facts and information as a Chemistry reference guide.

Cobalt - 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 and 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.
