Consider the following nuclear reactions: \( 1 . \frac{14}{7} N+_{2}^{4} H e \longrightarrow_{8}^{17} O+_{1}^{1} H \) 2. \( _{4}^{9} B e+_{1}^{1} H \longrightarrow_{3}^{9} L i+_{2}^{4} H e \) 3. \( _{\mathbf{1 2}}^{24} \boldsymbol{M} \boldsymbol{g}+_{\mathbf{2}}^{\mathbf{4}} \boldsymbol{H} \boldsymbol{e} \longrightarrow_{\mathbf{1 4}}^{\mathbf{2 7}} \boldsymbol{S} \boldsymbol{i}+_{\mathbf{0}}^{\mathbf{1}} \boldsymbol{n} \) 4. \( \frac{10}{5} \boldsymbol{B}+_{2}^{4} \boldsymbol{H} e \longrightarrow \frac{13}{7} \boldsymbol{N}+_{0}^{1} \boldsymbol{n} \) Examples of induced radioactivity would include the reactions:
- A. 3 and 4
- B. 1 and 2
- C. 1,3 and 4
- D. 1,2,3 and 4
Step-by-step solution
Reaction 2 as written does not conserve mass number (left: 9+1=10, right: 9+4=13), indicating a typo; the correct product is Li-6 (stable). Reactions 3 and 4 produce radioactive Si-27 and N-13, respectively, while reaction 1 produces stable O-17. Therefore, only reactions 3 and 4 are examples of induced radioactivity.
