Chapter 32, Problem 26PE

Verify that the total number at nucleons, total charge, and electron family number are conserved for each of the fusion reactions in the proton—proton cycle in ${}^1{\text{H+}}^1\text{H}{\to }^2\text{H+}{e}^{+}+v_e{,}^1{\text{H+}}^2\text{H}{\to }^3\text{H}e+\gamma$, and ${}^2{\text{H+}}^3\text{He}{\to }^4\text{H}{e}^{+}{+}^1{\text{H+}}^1\text{H}$. (List the value of each of the conserved quantities before and after each of the reactions.)
