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 3.71×10315O nuclei...

Radioactive Decay Objective: to study the radioactive decay of materials. Understand the concept of half life and randomness of the radioactive decay Run the case of H3 decay to He3: Go to “Multiple Atoms” tab Start with 80 atoms by clicking on the bucket. Start running and record the time when the number of H3 is changing to 40, 20, 10, and 5.This is accumulative time Repeat the above step 5 times and average them (below is an example of table...

Carbon 14 (C-14), a radioactive isotope of carbon, has a half-life of 5730 ± 40 years. Measuring the amount of this isotope left in the remains of animals and plants is how anthropologists determine the age of samples. Example: The skeletal remains of the so-called Pittsburgh Man, unearthed in Pennsylvania, had lost 82% of the C-14 they originally contained. Determine the approximate age of the bones assuming a half-life of 5730. (a) 14,000 years (b) 15,000 years (c) 17,000 years...
