Question

  1. A. It decreases by 1
  2. B. It increases by 1
  3. C. It remains unchanged
  4. D. It decreases by 2

Answer

The correct answer is B: It increases by 1.

Explanation

The correct answer is B: It increases by 1. This supports the learning objective "Balance atomic 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 by 1; It remains unchanged; It decreases by 2.

Common mistake

Common Mistake in Balancing Atomic Numbers

Students often forget to adjust both the mass number and atomic number when balancing nuclear equations, leading to incorrect representations of decay processes.

Always ensure that both the mass number and atomic number are balanced on both sides of the equation. Check that the total atomic number of reactants equals that of the products.
