The total number of $\alpha$ and $\beta$ particles emitted in the following radioactive decay is ____
\[ { }_{92}^{238} \mathrm{U} \rightarrow { }_{82}^{210} \mathrm{Pb} \]
Answer
Answer (as printed): 11

The options are missing from the source scan for this question, so there is nothing here for this letter to point at. The letter is what the book printed.

Explanation
Answer: 11 (7 α + 4 β) — Mass change 238 − 210 = 28, so 7 α. That alone gives Z = 92 − 14 = 78; reaching 82 needs 4 β⁻. Total 11.
