In addition, the element is widely used in the development of copper, bronzes, aluminum and cobalt. The word cobalt comes from the German "Kobolds" which means goblin or trouble maker. With the exception of the mining region, cobalt is not very abundant, with only trace amounts in the Earths crust (about 2500 times less than iron). In this area the huge multicoloured cobalt minerals deposits tower high, with the shores of dams and streams coloured deep rose with silvery blue veins running through. Phase at room temperature: Solid 6. Some of the most common uses for cobalt are: Blue paint for ceramics and glass, Magnets, and cutting tools. The regulus of Cobalt needs alkalies to precipitate, and then forms dark or black precipitates. These are alloys that retain mechanical strength at high temperatures. A huge reserve of several transition metals (including cobalt) can be found in strange nodules on the floors of the deepest oceans. It was discovered in 1735 by Georg Brandt, a Swedish chemist and mineralogist. Brandt was attempting to prove that the ability of certain minerals to color glass blue was due to an unknown element and not to bismuth , as was commonly believed at the time. Allotropes Cobalt: Discovered in 1739 by George Brandt 28. Cobalt is the metal at the centre of vitamin B, Cobalt has been known and used by people for its beautiful colouring and pigment properties as far back as 2500BC. Political stability of top reserve holder. He had been trying to demonstrate that the blue colour of glass was because of a new element, cobalt, rather than bismuth, an element often found in the same locations as cobalt. A vertical column in the periodic table. In addition to being used as a dye, cobalt is also important to human nutrition as it is an essential part of vitamin B12. It takes longer to log onto YA than it does to Google cobalt and then go to Wikipedia. A trace mineral is an element needed by plants and animals in minute amounts. Murray Robertson is the artist behind the images which make up Visual Elements. About 1741 he wrote: "As there are six kinds of metals, so I have also shown with reliable experiments... that there are also six kinds of half-metals: a new half-metal, namely Cobalt regulus[5] in addition to Mercury, Bismuth, Zinc, and the reguluses of Antimony and Arsenic". Silver was discovered in the area during the construction of the Temiskaming & Northern Ontario Railway (T&NO) from North Bay to the communities of Haileybury and … The role of the element in humans, animals and plants. Values are given for typical oxidation number and coordination. George Brandt was analyzing a dark blue pigment found in a copper ore, when he stumbled across the an undiscovered mineral. Radioactive cobalt-60 is used to treat cancer and, in some countries, to irradiate food to preserve it. The Chemical Abstracts Service registry number is a unique identifier of a particular chemical, designed to prevent confusion arising from different languages and naming systems.

It is widely used in cancer treatment, as a tracer and for radiotherapy. A lustrous, silvery-blue metal. It is important in the formation of red blood cells. The attacker’s post compromise activity leverages multiple techniques to evade detection and obscure their activity, but these efforts also offer some opportunities for detection. It is one of only 3 ferromagnetic transition elements along with iron and nickel. A measure of how difficult it is to deform a material. It is an important source of gamma-rays. “People are still looking for the new cobalt blue, or the new lead white or titanium white, whatever it might be,” says St. Clair. These values were determined using several different methods. The solution was at hand and Cobalt found its salvation in the mineral for which the town was named – the mineral which, mixed with the silver ore had been only a nuisance, making the smelting and refining operations much more difficult. For many years his claim to have uncovered a new metal was disputed by other chemists who said his new element was really a compound of iron and arsenic, but eventually it was recognised as an element in its own right. He was able to show that cobalt was the source of the blue color in glass, which previously had been attributed to the bismuth found with cobalt. The market value of the metal depends on demands. Density is the mass of a substance that would fill 1 cm3 at room temperature. When converted to ounces, the element was trading at 1.47 per ounce. Cobalt is found in the minerals cobaltite, skutterudite and erythrite. Block Too much or too little cobalt in the body can cause health issues. Cobalt was – in the opinion of most observers a dying town. Most cobalt is formed as a by-product of nickel refining. Where more than one isotope exists, the value given is the abundance weighted average. Iron has been mined and used since 3000 BC, but who actually discovered it is something that is still unknown. Stop the proverbial "man in the street" and ask him what ruthenium is and the chances are he won't be able to tell you. W.E. The availability of suitable substitutes for a given commodity. Discovered by. Sources Cobalt occurs in the minerals cobaltite, smaltite, and erythrite, and is often associated with nickel, silver, lead, copper, and iron. It provides a measure of how difficult it is to extend a material, with a value given by the ratio of tensile strength to tensile strain. Who discovered technetium? Cobalt was discovered by Georg Brandt, a Swedish chemist, in 1735. Cobalt is a small mining town in Ontario which is well-known for its large deposits of silver, and has a very interesting geologic history. Values are given for typical oxidation number and coordination. Compared to the "sexier elements" that are household names like carbon and oxygen, ruthenium is, frankly, a bit obscure. As these things often go, Snyder discovered the tarantula almost by accident. The amount we need is very small, and the body contains only about 1 milligram. Radioactive cobalt-60 was discovered by Glenn T. Seaborg and John Livingood at the University of California - Berkeley in the late 1930's. Cobalt-60, radioactive isotope of cobalt used in industry and medicine. It produces 60% of the world's cobalt - a fifth of which is extracted by hand or artisanal miners known locally as creusseurs.
