59Co. The isotopes of cobalt range in atomic weight from 50 amu (50Co) to 73 amu (73Co). The primary decay mode before the most abundant stable isotope, 59Co, is electron capture and the primary mode after is beta decay. How abundant is cobalt-60?

Cobalt is a trace element in plants (it has not been proven to be essential for plant life). It is a component of a number of enzymes and increases the drought resistance of seeds. In legumes, cobalt is important for nitrogen fixation by the bacteria that associate with legumes. Is Read more…
Only certain forms of cobalt metal are pyrophoric.Pyrophoric cobalt is a black powder that burns brilliantly when in contact with oxygen or air. What are examples of pyrophoric materials? Pyrophoric substances are highly reactive chemicals that spontaneously ignite when exposed to air, examples include t-BuLi, potassium hydride (KH) and white Read more…
metal. Cobalt is a lustrous very hard silvery metal belonging to a group called the “transition metals”. It is one of only 3 ferromagnetic transition elements along with iron and nickel. Is Co a nonmetal? The metals are to the left of the line (except for hydrogen, which is a Read more…
Cobalt, as a trace element, is essential for rumen microorganisms for the formation of vitamin B12. In the metabolism of mammals, vitamin B12 is an essential part of two enzymatic systems involved in multiple metabolic reactions, such as in the metabolism of carbohydrates, lipids, some amino acids and DNA. What Read more…
In addition, lithium, cobalt, nickel, copper, zinc, niobium, molybdenum, lanthanum, europium, tungsten, and gold have been found in trace amounts. Does Mars have any metals? Mars has electrically charged metal atoms (ions) high in its atmosphere, according to new results from NASA’s MAVEN spacecraft. The metal ions can reveal previously Read more…
A l-oz sample of peanuts and peanut butter supplies 4.9% and 6.7% of the RDA for phosphorus (Anon., 1974). In general, foods have only traces of cobalt. The amount of cobalt in peanut butter was found to be 0.11 mg/lOOg. What foods are highest in cobalt? Good food sources of Read more…
The lack of industry regulation allows exploitative practices to continue, but it also presents a public health crisis. Without the proper safety gear, miners of all ages experience continuing exposure to dust and particles that result in lung and skin diseases, like tuberculosis or dermatitis. What are the dangers of Read more…
