A deutron strikes `._8 O^16` nucleus with subsequent emission of an alpha particle. Idenify the nucleus so produced.

Explanation

The nuclear reaction may be expressed as under
`._8O^16 + ._1H^2 to ._zX^A + ._2He^4 (alpha-"particle")`
Law of conservation of charge 8+1=Z+2 `rArr` Z=7
The atomic number of the element is 7 `rArr` element is nitrogen
Law of conservation of mass number 16+2 =A+4
A=14
`._zX^A=._7N^14` .
