When \({ }^{10} \mathrm{~B}_5\) nuclei are bombarded by neutrons, one of the resultant nuclei is \({ }^7 \mathrm{Li}_3\). Then the emitted particle will be:
- A Beta particle
- B Gamma particle
- C Neutrons
- D Alpha particle
Answer & Solution
Correct Answer
(D) Alpha particle
Step-by-step Solution
Detailed explanation
The nuclear reaction can be represented as follows: \({}^{10}_{5}\text{B} + {}^{1}_{0}\text{n} \rightarrow {}^{7}_{3}\text{Li} + {}^{A}_{Z}\text{X}\) Applying the law of conservation of mass number (A): \(10 + 1 = 7 + A \Rightarrow 11 = 7 + A \Rightarrow A = 4\) Applying the law…
