During mean life of a radioactive element
Webmean life, in radioactivity, average lifetime of all the nuclei of a particular unstable atomic species. This time interval may be thought of as the sum of the lifetimes of all the individual unstable nuclei in a sample, divided by the total number of unstable nuclei present. half-life, in radioactivity, the interval of time required for one-half of the atomic nuclei … decay constant, proportionality between the size of a population of radioactive atoms … WebSo the life of radioactive atoms ranges from 0-infinity mean life gives the sum of the life of all the atoms to the total no. of atoms present initially. The life which is obtained when …
