Chapter 4.4, Problem 26SSC

Interpretation Introduction

Interpretation:  Quantities that are conserved while balancing a nuclear reaction needs to be explained.

Concept introduction:  Nuclear reaction is a process that involves the collision of two nuclei or nuclear particles that produces a different product than initial particles.

Answer to Problem 26SSC

When balancing a nuclear reaction, mass number and atomic numbers are conserved.

Explanation of Solution

In a balanced chemical reaction, old bonds break to form new bonds and in this process rearrangement of atoms takes place. There is no change in the total numbers of atoms of each element.

Thus, in a balanced nuclear reaction, the sum of the mass numbers and the sum of the atomic numbers of reactants and product is balanced. The sum of charges is also same on both sides of the reaction arrow.

Conclusion

Thus, mass number and atomic number are conserved when balancing a nuclear reaction.
