Question

  1. A. It ensures the equation is correct
  2. B. It indicates the type of radiation emitted
  3. C. It shows the energy released
  4. D. It determines the half-life

Answer

The correct answer is A: It ensures the equation is correct.

Explanation

The correct answer is A: It ensures the equation is correct. 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 indicates the type of radiation emitted; It shows the energy released; It determines the half-life.

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.
