Chapter 25.9, Problem 5Q

Interpretation Introduction

Interpretation:

The particle produced in the decay process of ${}_{\text{43}}^{\text{99}}\text{Tc}$ to ${}_{\text{44}}^{\text{99}}\text{Ru}$ has to be predicted.

Concept interpretation:

Balancing nuclear reaction equation: The balanced nuclear reaction should conserve both mass number and atomic number.

• The sum of the mass numbers of the reactants should be equal to the sum of mass numbers of the products in the reaction.
• The sum of atomic numbers (or the atomic charge) of the reactants should be equal to the sum of atomic numbers (or the atomic charge) of the products in the reaction.
