Q.
$_{2}^{4}{He} +_{4}^{9}{Be} \rightarrow \ _{0}^{1}n + \ ?$
The missing ion in the above nuclear reaction is
A) proton
B) Oxygen-12
C) Carbon-12
D) Nitrogen-12
Explanation
(c) From the conservation of mass number and charge number
$\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ _{2}^{4}{He} +_{4}^{9}{Be} \rightarrow_{0}^{1}n +_{6}^{12}X$
Here, $X$ can be carbon.
