Cobalt was the birthplace of Canadian hard rock mining Cobalt, Ontario, played an important role in the evolution of the mining and financial industries in Canada. Silver was discovered in the area in the summer of 1903, during construction of the Temiskaming and Northern Ontario Railway. Where is cobalt found Read more…
Silver-white. Common elements Symbol Name Color Cd Cadmium Brick red Ce Cerium Yellow Co Cobalt Silver-white Cr Chromium Silver-white What happens when you burn cobalt? Cobalt is somewhat of a reactive element. It combines with oxygen in the air, but does not catch on fire and burn unless it is Read more…
Cobalt, like iron, can be magnetised and so is used to make magnets. It is alloyed with aluminium and nickel to make particularly powerful magnets. Other alloys of cobalt are used in jet turbines and gas turbine generators, where high-temperature strength is important. What’s cobalt used for? Cobalt is commonly Read more…
Cobalt has fifteen electrons in its third shell that holds a maximum of eighteen electrons (as seen in zinc). How many electrons are in each shell of cobalt? Cobalt has a total of 27 electrons. There are two valence electrons in the 4s energy level, seven electrons in the 3d, Read more…
Cobalt therapy is the medical use of gamma rays from the radioisotope cobalt-60 to treat conditions such as cancer. Beginning in the 1950s, cobalt-60 was widely used in external beam radiotherapy (teletherapy) machines, which produced a beam of gamma rays which was directed into the patient’s body to kill tumor Read more…
Cobalt salts have been used for centuries to produce brilliant blue colours in paint, porcelain, glass, pottery and enamels. Radioactive cobalt-60 is used to treat cancer and, in some countries, to irradiate food to preserve it. Cobalt is an essential trace element, and forms part of the active site of Read more…

Cobalt-60 is used as a radiation source in medical therapy. Cobalt-60 emits gamma rays which are used in teletherapy for treating cancer. Hence, we can say that cobalt-60 is used in treating cancer. Therefore, the correct option is D. Why is Cobalt 60 used in cancer treatment? Co-60 is used Read more…
What is it used for? Co-60 is used medically for radiation therapy as implants and as an external source of radiation exposure. Is cobalt treatment still used? Because these “cobalt machines” were expensive and required specialist support, they were often housed in cobalt units. Cobalt therapy was a revolutionary advance Read more…
