When a ^{14}\text{N}

nucleus is bombarded with an

\alpha

-particle, a ^{17}\text{O}

nucleus is produced along with the emission of another particle. The emitted particle is a

Options

Apositron
Belectron
Cneutron
Dproton

Correct answer

D. proton

Step-by-step solution

The nuclear reaction can be written as:

^{14}_{7}\text{N} + ^{4}_{2}\text{He} \rightarrow ^{17}_{8}\text{O} + ^{A}_{Z}\text{X}

<br><br>Applying the law of conservation of mass number:<br><br>

14 + 4 = 17 + A

<br><br>

A = 1

<br><br>Applying the law of conservation of atomic number:<br><br>

7 + 2 = 8 + Z

<br><br>

Z = 1

<br><br>The particle with mass number

and atomic number

is a proton (^{1}_{1}\text{p}
