Atoms and nuclear radiation
Question
- A. It decreases both mass number and atomic number
- B. It increases mass number by 1
- C. It does not change mass number or atomic number
- D. It decreases atomic number by 2
Answer
The correct answer is C: It does not change mass number or atomic number.
Explanation
The correct answer is C: It does not change mass number or atomic number. This supports the learning objective "Balance mass numbers in 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: It decreases both mass number and atomic number; It increases mass number by 1; It decreases atomic number by 2.
Common mistake
Common Mistake in Balancing Nuclear Equations
Students often forget to balance both the mass number and atomic number when writing nuclear equations, leading to incorrect representations of decay processes.
Always check that the sum of the mass numbers and the sum of the atomic numbers on both sides of the equation are equal. Practice with examples to reinforce this skill.
