Atomic symbol (on the Periodic Table of Elements): Co Atomic weight (average. Cobalt blue is a vivid color used in artwork. Visit Bodycote’s new Interactive Periodic Table to view this information and more graphically. Some common forms of cobalt include cobalt-60 and cobalt chloride.

Cobalt-60 has a of 5.27 years and decays into nickel-60 through beta decay. The number of protons define the identity of an element (i.e., an element with 6 protons is a carbon atom, no matter how many neutrons may be present). Cobalt-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. The atomic number is the number of protons in the nucleus of an atom. Visit Bodycote’s new Interactive Periodic Table to view this information and more graphically. In the modern periodic table, the elements are listed in order of increasing atomic number. In those cases, the origin of the symbol used is given. A very few elements have symbols which appear to have no relationship with their names. In some cases, the first letter together with some other letter from their name was used, particularly when their first two letters had already been allocated to another element. Most chemical elements are represented symbolically by two letters, generally the first two in their name. Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images. Powdermet® Selective surface net shape (SSNS)Īnti-Slavery and Human Trafficking Statement Element Iron (Fe), Group 8, Atomic Number 26, d-block, Mass 55.845. Sub-critical annealing / intercritical annealing All other isotopes have half-lives of less than 18 hours and most of these have half-lives of less than 1 second. Twenty-eight radioisotopes have been characterized the most stable are 60 Co with a half-life of 5.2714 years, 57 Co (271.8 days), 56 Co (77.27 days), and 58 Co (70.86 days). As with nickel, cobalt is found in the Earths crust only in a chemically combined. Specialty Stainless Steel Processes (S 3P) Naturally occurring cobalt (27 Co) consists of a single stable isotope, 59 Co. Cobalt is a chemical element with the symbol Co and atomic number 27.
