Q70 / 180 · AIIMS 2015 · Chemistry

In a decay process ${ }_Z^A X$ changes into ${ }_{Z-1}^A Y$. Which process is this?

  • A
    $\beta$-decay
  • Correct answer
    B
    $\beta^{+}$-decay
  • C
    $\alpha$-decay
  • D
    $\gamma$-decay.

Solution

${ }_Z^A X \longrightarrow{ }_{Z-1}^A Y+{ }_{+1}^0 e\left(\right.$ or $\left.\beta^{+}\right)$

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