They have created a complete suite of short videos on every element on the periodic table of elements. If the chemical symbol has two letters the first letter is always capitalised and the second letter is written in lowercase. Cobalt is a chemical element with symbol Co and atomic number 27. The video below is from the University of Nottingham's periodic videos project. Cobalt has only one isotope found in nature: Symbol It was discovered and first isolated in 1735 by Georg Brandt. Radioactive isotopes of cobalt tend to have very short half lives, most of which are less than 24 hours. Cobalt is a chemical element that is a hard and lustrous metal, silver gray in color. This isotope is used for radiotherapy, as a medical tracer, and to sterilize medical equipment through irradiation. Radioactive cobalt-60 is a commonly used medical isotope. Lithium cobalt oxide is one of the lithium oxides commonly used in rechargable lithium batteries. Cobalt alloys are used to make items that need high strength and corrosion resistance such as magnets, jet and gas turbine generators, surgical implants, and prosthetics. Cobalt is most commonly used as part of an alloy though. There are various synthetic isotopes of cobalt, but the most abundant naturally occurring stable isotope is the 59 Co. Pure cobalt metal is sometimes used for electroplating because it is hard and corrosion resistant. The melting point of cobalt is 1495 ☌ and its boiling point is 2927 ☌. Ĭobalt salts have long been used to create the distinctive blue colour for porcelain (Figure 2), as well as for enamel and paints, pottery, and glass. Cobalt blue Chinese porcelain from the 1400s. ![]()
