Common Questions and Their Answers in a Nuclear Physics Webquest Answer Key
Q1: What is the difference between nuclear fission and fusion?
Answer: Nuclear fission involves splitting a heavy nucleus into smaller nuclei, releasing energy, as seen in nuclear reactors. Fusion combines light nuclei, such as hydrogen isotopes, to form a heavier nucleus, releasing vast amounts of energy, as occurs in the sun.
Q2: How is half-life used to determine the age of a radioactive sample?
Answer: By measuring the remaining amount of a radioactive isotope and knowing its half-life, scientists can calculate the time elapsed since the sample was formed, which is useful in radiometric dating.
Q3: Why is nuclear stability important?
Answer: Stable nuclei do not undergo spontaneous decay, ensuring safety and consistency in applications. Unstable nuclei decay over time, releasing energy and radiation, which can be harnessed or require safety precautions.
Q4: What safety measures are necessary when working with radioactive materials?
Answer: Proper shielding, minimizing exposure time, using protective gear, and following protocols for storage and disposal are essential to ensure safety.
