WebRadioactive. This is the first half life. 4. Place the atoms that didn’t decay (candies with “m” facing up) back into the cup and shake for another 10-sec time interval. Record the number of “radioactive” atoms remaining. This is the 2nd half life. 5. Keep repeating time interval trials until all atoms have decayed. Add additional ... Webing, you need to know the half-life of the parent isotope. The half-life of a radioactive isotope is how long it takes for half of a sample of the isotope to decay. For example, imagine that a parent isotope has a half-life of 10,000 years. A sample of this isotope has a mass of 12 mg. After 10,000 years, only one-half, or 6 mg, of the sample
