WebNaturally occurring cobalt (27 Co) consists of a single stable isotope, 59 Co. 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). All other isotopes have half-lives of less than 18 hours and most of these have half-lives of less than 1 … WebA radioactive half-life refers to the amount of time it takes for half of the original isotope to decay. For example, if the half-life of a 50.0 gram sample is 3 years, then in 3 years only 25 grams would remain. During the next 3 years, 12.5 grams would remain and so on.

WebSo 14.3 days is the half-life of phosphorus-32. And this is the symbol for half-life. So, 14.3 days is the half-life for phosphorus-32. The half-life depends on what you're talking about. So if you're talking about something like uranium-238, the half-life is different, it's approximately 4.47 times 10 to the ninth, in years.
