Question

A nuclear reaction is given as
$p{+}^{15}N{\to }_Z^{A}X+n$
Find, A, Z and identify the nucleus X.

Answer 1

The nuclear reaction will be ${}_1^{1}p{+}_7^{15}N{=}_Z^{A}X{+}_0^{1}n$

Now, $1+15=A+1\Rightarrow A=15$ and $1+7=Z+0\Rightarrow Z=8$

The nucleus would be isotope of oxygen i.e ${}_8^{15}O$
