- A. Alpha particles
- B. Beta particles
- C. Gamma rays
- D. All of the above
Answer
The correct answer is D: All of the above.
Explanation
The correct answer is D: All of the above. This supports the learning objective "Explain that unstable nuclei may emit radiation to become more stable." in Mass number, atomic number and isotopes because it uses the correct atomic and nuclear radiation relationship for Atoms and isotopes. The other options are less suitable because they do not match the required Mass number, atomic number and isotopes idea: Alpha particles; Beta particles; Gamma rays.
Common mistake
Misunderstanding Radiation Emission
Students often think that all unstable nuclei emit radiation at the same rate, not recognizing that the rate of emission varies for different isotopes.
Emphasize that the rate of radiation emission is specific to each isotope and is related to its half-life, which indicates how quickly it becomes stable.
