For the first question regarding an appropriate model of the radioactive decay of a group of atoms, the best option would be:
**Popping a bag of popcorn.**
This is because, like radioactive decay, popping popcorn happens unpredictably over time; some kernels pop while others don’t, much like how individual atoms decay at different rates.
For the second question regarding the effect of radioactive decay on a nucleus, the best statement is:
**The resulting nucleus is more stable than the original nucleus. The nucleus can be of a different element than the original.**
In radioactive decay, the original unstable nucleus transforms into a more stable form, which can often result in a new element (such as when uranium decays into lead).
