31.4 Exercise 33

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 $Z$.

Calculate the energy released in the $\beta^{+ }$ decay of $^{\text{22}} \text{Na}$, the equation for which is given in the text. The masses of $^{\text{22}} \text{Na}$ and $^{\text{22}} \text{Ne}$ are 21.994434 and 21.991383 u, respectively.
