A nuclear transformation is denoted by X(n,α)37LiX(n, \alpha){ }_3^7 \mathrm{Li}. Which of the following is the nucleus of element XX ?

Options

  1. A12C6{ }^{12} \mathrm{C}_6
  2. B510 B{ }_5^{10} \mathrm{~B}
  3. C59 B{ }_5^{9} \mathrm{~B}
  4. D411 Be{ }_4^{11} \mathrm{~Be}

Correct answer

B. 510 B{ }_5^{10} \mathrm{~B}

Step-by-step solution

X+01n→24He+37Li\mathrm{X}+{ }_0^1 \mathrm{n} \rightarrow{ }_2^4 \mathrm{He}+{ }_3^7 \mathrm{Li}
