In addition to being used as a dye, cobalt is also important to human nutrition as it is an essential part of vitamin B 12.Įstimated Crustal Abundance: 2. The atomic number of each element increases by one, reading from left to right. Period A horizontal row in the periodic table. Members of a group typically have similar properties and electron configurations in their outer shell. Cobalt is used in many alloys & super alloys to make parts in aircraft engines, gas turbines, high-speed steels, corrosion-resistant alloys, and cemented carbides. Some of these compounds are known as: cobalt blue, ceruleum, new blue, smalt, cobalt yellow and cobalt green. Cobalt 27 58.933 Glossary Group A vertical column in the periodic table. for the reactants are CO, and H, O, while for the product is H, CO. Find physical data, electron configuration, chemical properties, aggregation states. Name Number of of the atoms in Number of atoms in element reactants products H. So you know that to get a zero sum rule Co. Look at Nitrogens oxidations: 2, (+-)3, 4, 5. Cobalt-60 has a half-life of 5.27 years and decays into nickel-60 through beta decay.Ĭobalt compounds have been used for centuries to color porcelain, glass, pottery, tile and enamel. Get the facts about element Cobalt (Co) 27 from the periodic table. Cobalt is multivalent and so you have to look at its oxidation states: 2,3. Uses: used for casts to hold broken limbs in place, modelling casts, sculptures and in plasterboard walls and ceilings. Cobalt is also used to make alloys for jet engines and gas turbines, magnetic steels and some types of stainless steels.Ĭobalt-60, a radioactive isotope of cobalt, is an important source of gamma rays and is used to treat some forms of cancer and as a medical tracer. Uses: Potash is the common name for various mined and manufactured salts that contain potassium in water-soluble form. Stellite alloys, which contain cobalt, chromium and tungsten, are used to make high-speed and high temperature cutting tools and dyes. Alnico, an alloy consisting of aluminum, nickel and cobalt is used to make powerful permanent magnets. A chemical element, often simply called an element, is a type of atom which has the same number of protons in its atomic nucleus (i.e., the same atomic number, or Z ). Cobalt is usually recovered as a byproduct of mining and refining nickel, silver, lead, copper and iron.Īlthough cobalt is used in electroplating to give objects an attractive surface that resists oxidation, it is more widely used to form alloys. This is a list of the 118 chemical elements that have been identified as of 2023. Cobalt's primary ores are cobaltite (CoAsS) and erythrite (Co 3(AsO 4) 2). 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. Cobalt was discovered by Georg Brandt, a Swedish chemist, in 1739.
