MCQ
Which decay increases the atomic number?
  • A
    $\beta^-$decay
  • B
    $\beta^+$ decay
  • C
    Electron capture
  • D
    Gamma decay

Answer

  1. $\beta^-$decay

Explanation:

$\beta^-$ decay: $_\text{Z}^\text{A}\text{​X}→_{\text{Z}+1}^{\text{A}}\text{​Y} + _{−1}^0\text{​e}$

Thus, the atomic number is increased in $\beta^-$ decay.
