1. How many trials did it take for half of the Virtualium atoms to decay?
2. Suppose each trial equals 1,000 years. What is the half-life of Virtualium?
3. Suppose each trial equals 1,000 years. After half (50) of the Virtualium cubes were removed from the box, about how long did it take for half of the rest of the cubes to decay?
4. Imagine you have a radioactive sample containing both Virtualium and decayed atoms of Virtualium. After analysis, you find it contains 10 atoms of Virtualium and 40 decayed atoms. How old is your sample? (Hint: You must use the half-life of Virtualium determined earlier in the activity.)
