Cobalt is an essential trace element since it is the core component of vitamin B12. There is no dietary recommendation related to cobalt itself because vitamin B12 cannot be synthetized in the human body and must be ingested as such [81]. Apart from this role, cobalt is not known to play...

Cobalt'satomic number(number of protons in its nucleus) is 27. Itsrelative atomic massis 58.933200. An element's relative atomic mass equals itsmass(amount of matter) divided by1/12of the mass of an atom of carbon 12, the most abundant form of carbon. Cobalt has a density of 8.9 grams...
only stable isotope, 59Co, is electron capture and the primary mode of decay in isotopes with atomic mass greater than 59 atomic mass units is beta decay. The primary decay products below 59Co are element 26 (iron) isotopes; above that the decay products are element 28 (nickel) isotopes....

Cobalt is an element that occurs naturally in the environment in air, water, soil, rocks, plants and animals. It may also enter air and water and settle on land through wind-blown dust and enter surface water through run-off when rainwater runs through soil and rock containing cobalt. Human...
