Q181 / 200 · Manipal (MET) 2010 · Physics

In the reaction ${ }_7 \mathrm{~N}^{14}+\alpha \longrightarrow{ }_8 X^{17}+{ }_1 p^1$ identify $X$.

  • Correct answer
    A
    $\mathrm{O}_2$
  • B
    $\mathrm{N}_2$
  • C
    He
  • D
    Ar

Solution

In the reaction ${ }_7 \mathrm{~N}^{14}+\alpha \longrightarrow{ }_8 X^{17}+{ }_1 p^1$ 8 is the atomic number of oxygen molecule. So, here $X$ is oxygen $\left(\mathrm{O}_2\right)$ molecule.

Hence, the correct answer is option: 'A'.
