A nuclear transformation is denoted by $X(n,α)→{_3^{7}Li}$. Which of the following is the nucleus of element X?
Answer & explanation
Correct answer: option 2
$\text{The notation denoted means that when a nucleus X is bombarded with neutron then it breaks in to Lithium and }\alpha { particle}$.
$ Z-2 = 3 \text{ and } A - 3 = 7$
$\rightarrow Z = 5 , A = 10$
