Which one of the following particles is used to bombard to give and a neutron? — Nuclear Chemistry and Radioactivity Chemistry Question

💡 Solution & Explanation

The reaction is ${}_{13}\text{Al}^{27} + {}_Z\text{X}^A \to {}_{15}\text{P}^{30} + {}_0\text{n}^1$. Equating mass numbers: $27 + A = 30 + 1 \implies A = 4$. Equating atomic numbers: $13 + Z = 15 + 0 \implies Z = 2$. This particle (${}_2\text{He}^4$) is an alpha particle. Therefore, correct answer is C.
