Chapter 20, Problem 30E

Write a nuclear reaction for each step in the formation of $\text{P}\text{b}$ from $\text{T}\text{h}$, which proceeds by a series of decay reactions involving the step-wise emission of a, $\text{α,}\text{α,}\text{α,}\text{α},\text{β},\text{β},\text{α}$ particles, in that order.
