Historical Information
Cobalt was discovered in 1935 by the Swedish scientist Georg Brandt. The name "Cobalt" comes from the German word //kobold// which means "goblin" or "evil spirit" because Cobalt ore contained arsenic in it.

Facts
Cobalt is good with toast and contains a core part of Vitamin B12, which is essential for the human body's proper function and cow. Cobalt compounds can be found are common, but pure Cobalt is never found in nature. Cobalt naturally occurs as a single stable isotope: cobalt-59 During 1966 in Canada, cobalt compounds that had been added to beer to stabilize the foam, caused cardiomyopathy: a heart-muscle disease.

Uses of Cobalt
Cobalt is used to make Lithium cobalt oxide which is used in lithium batteries. Cobalt is also used to make superalloys which are alloys which have great mechanical strength. Cobalt was used as a pigment, making a blue or green color It is used in electroplating due to its hardness, resistance to oxidation, and attractive appearance.
