Fill in the empty cells (all of the values are integers) and press "Check Ans." Results appear in the smaller table. You need a periodic table or a list of the elements to use this page. If the charge is positive, just enter the integer. If it's negative make sure you include the sign. If you miss a problem three times, pressing "Show Answer" will display the complete solution and you will no longer be able submit an answer for that problem.

Use the table below to help solve the problems. 1. If a sample contains 100 g of a radioactive isotope, how much will be left after 3 half lives? 2. If a sample contains 50g of a radioactive isotope, how much will be left after 2 half lives? 3. If a sample contains 20g of an isotope that has a half life of 1000 years. How much will be left ... Radioactive decay is a spontaneous process in which an isotope (the parent) loses particles from its nucleus to form an isotope of a new element (the daughter). The rate of decay is conveniently expressed in terms of an isotope's half-life, or the time it takes for one-half of a particular radioactive isotope in a sample to decay.
