This means that it was discovered after modern language was invented, so that the information (such as the name of the discoverer) could be written down.Ĭompound cobalt-60 is used in the production of radioactive emissions used in chemotherapy to help treat cancer and used in the cleaning and sterilizing process of medical tools. It was the first metal to be discovered that occurred recently enough in history that we know the name of the person that discovered it. More facts about cobaltĬobalt was the first metal to be discovered after the development of civilization, after the prehistoric era. Mined cobalt is used as a dye for blue coloring in various ink, paint, ceramic and glasswork, and sometimes cosmetic products.Īncient Chinese and Roman glass- and ceramic-making techniques often used to include compounds of cobalt.īecause of cobalt’s magnetic properties, it can also be used in the creation and production of batteries, magnets, and other industrial equipment. Most of cobalt mining is done on the African continent, and these mining efforts tend to include the mining of nickel, iron, copper, lead, and silver as well. It is not generally found freely around the planet Earth, but it can be mined from various other minerals and rock from the Earth’s outer crust. The human body, along with other animal bodies, use naturally-occurring cobalt to create important chemicals in the body, such as enzymes.Ĭobalt is one component of the well-known, important vitamin B12.Ĭobalt was discovered by George Brandt in the year 1735. Interestingly, cobalt is also important in the survival of living organisms. In general, cobalt is resistant to corrosion, rust, and other damage. Cobalt primarily appears as a hard, breakable metal that looks blue and white in color.Ĭobalt’s atomic number is 27, of course, and its atomic weight is 58.93.Īt room temperature, cobalt is a solid, and its melting point is very high at 1495 degrees Celsius.Ĭobalt also has magnetic properties, and continues retain these magnetic properties even when heated to very high temperatures.Ĭobalt is only very minorly reactive, and any reaction that it has from being exposed to oxygen occurs very slowly.Ĭompounds can be formed in the combinations of cobalt and other elements, leading to cobalt oxide, cobalt fluoride, and cobalt sulfide.īecause the melting point of cobalt is so high and has little to no reaction to oxygen, it is considered to be very stable at even very high temperatures. Atoms of cobalt are known to have 27 protons, 27 electrons, and 32 neutrons. Cobalt is an element from the periodic table of elements that falls into the ninth column of the table.Ĭobalt is considered a transition metal due to its location on the periodic table and some of its properties as a metal.
