31.4 Exercise 25

In the following four problems, identify the parent nuclide and write the complete decay equation in the $_{Z}^{A} X_{N}$ notation. Refer to the periodic table for values of $Z$.

Confirm that charge, electron family number, and the total number of nucleons are all conserved by the rule for $\beta^{- }$ decay given in the equation $_{Z}^{A} X_{N} \rightarrow _{Z + 1}^{A} \text{Y}_{N - 1} + \beta^{- } + \left(\bar{\nu}\right)_{e}$. To do this, identify the values of each before and after the decay.
