Answer #1

so for deacay the nuclei before 50% time will be less then half life less then 20 yrs .according to given information answer will be less then 20yrs complete information is not given.

Thanks!please rate it up

The half-life of a radioactive isotope represents the average time it would take half of a collection of this type of nucleus to decay. For example, you start with a sample of 1000 Oxygen-15 (15O) nuclei, which has a half-life of 122 seconds. After 122 seconds, half of the 15O nuclei will have decayed into Nitrogen-15 (15N) nuclei. After another 122s, half of the remaining Oxygen nuclei will have also decayed, and so on. Suppose you start with 4.00×103 15O...

Given the fact that the lifetime of 14C, the radioactive isotope of carbon, is approximately 8267 years, calculate how much time would pass before only 81.1% of the initial amount of the 14C remains. (Note: the lifetime = half life/ln (2) = half life/0.6931. The half life of 14C is 5730 years.) Decay Time (in years):
