Read each question carefully and provide your best answer. Show all work where applicable.
1. Which of the following best describes nuclear fission?
The combining of two light nuclei to form a heavier nucleus.
The splitting of a heavy nucleus into two or more smaller nuclei.
The emission of alpha particles from a radioactive nucleus.
The spontaneous decay of an unstable atomic nucleus.
2. What is a primary challenge in achieving controlled nuclear fusion on Earth?
The lack of available fuel sources.
The difficulty in maintaining extremely high temperatures and pressures.
The production of large amounts of radioactive waste.
The limited energy output compared to fission reactions.
3. Nuclear fission is initiated when a heavy atomic nucleus, such as Uranium-235, absorbs a , causing it to become unstable and split.
4. The process of nuclear fusion releases a tremendous amount of energy because some of the mass of the reacting nuclei is converted into energy, as described by Einstein's famous equation, E = .
5. Nuclear fusion reactions produce highly radioactive waste products that remain dangerous for thousands of years.
True
False
6. The sun's energy is primarily generated through nuclear fission reactions occurring in its core.
True
False
7. Briefly explain the concept of a chain reaction in the context of nuclear fission.
8. Observe the diagram below, which illustrates a simplified atomic nucleus. If this nucleus were to undergo fission, what would be the expected outcome in terms of its constituent parts?
