Charkiba Robinson Chemistry Period 2

Cobalt was discovered 1739 by George Brandt in Sweden. The word “cobalt” originated from the German word, “kobald.” (goblin; evil spirit)

Cobalt is lustrous. Silvery-blue metal Cobalt is magnetic.

Cobalt has one naturally occurring isotope. This isotope is cobalt-59 Cobalt is somewhat reactive. Cobalt does not catch on fire unless it is in powder form. Cobalt has the ability to react with acids to produce hydrogen gas.

Cobalt is an essential trace element. Cobalt forms part of the active site of B12(a vitamin) Cobalt-60(radioactive isotope) is an important source of gamma-rays.

Water ( at room temperature) Acids Oxygen Iron Copper Nickel Zinc

Cobalt oxide Cobalt potassium nitrite Cobalt aluminate Cobalt ammonium phosphate

Cobalt is special because it is vital to have a certain amount in the body for nutrition. Cobalt is the first metal to have a recorded discovery date. Cobalt is used to treat cancer.
