Question
- A. The emission of alpha radiation
- B. The emission of beta radiation
- C. The emission of gamma radiation
- D. No change in the nucleus
Answer
The correct answer is B: The emission of beta radiation.
Explanation
The correct answer is B: The emission of beta radiation. This supports the learning objective "Identify the type of radiation emitted from the change in mass number and atomic number." in Nuclear equations because it uses the correct atomic and nuclear radiation relationship for Atoms and nuclear radiation. The other options are less suitable because they do not match the required Nuclear equations idea: The emission of alpha radiation; The emission of gamma radiation; No change in the nucleus.
Common mistake
Confusing Radiation Types
Students often confuse the types of radiation emitted based on changes in mass number and atomic number.
To fix this, students should practice identifying the changes in mass and atomic numbers for each type of radiation (alpha, beta, gamma) and relate them to the corresponding nuclear equations.
