Determine the product when Th 234 90 undergoes two beta emissions ( e 0 1 ) followed by two alpha emissions ( He 4 2 ). Write nuclear equations for each of the four steps in the process. (You should show the isotopes formed by each step of the decay process).

The final product is Ra 226 88
Steps of the decay process: 1) Th 234 90 → Pa 234 91 + e 0 -1 2) Pa 234 91 → U 234 92 + e 0 -1 3) U 234 92 → Th 230 90 + He 4 2 4) Th 230 90 → Ra 226 88 + He 4 2
