Atoms and nuclear radiation
Question
- A. They only need to balance mass numbers.
- B. They must balance both charge and nucleon number.
- C. They can ignore charge conservation.
- D. They are not affected by decay processes.
Answer
The correct answer is B: They must balance both charge and nucleon number..
Explanation
The correct answer is B: They must balance both charge and nucleon number.. This supports the learning objective "Apply conservation of charge and nucleon number when checking nuclear equations." 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: They only need to balance mass numbers.; They can ignore charge conservation.; They are not affected by decay processes..
Common mistake
Common Mistake in Nuclear Equations
Students often forget to balance both the mass number and atomic number when checking nuclear equations.
Always check that the total mass numbers and total atomic numbers on both sides of the equation are equal to ensure conservation of nucleon number and charge.
