Q174 / 180 · KCET 2015 · Physics

A radioactive decay can form an isotope of the original nucleus with the emission of particles

  • A
    one \( \alpha \) and four \( \beta \)
  • Correct answer
    B
    one \( \alpha \) and two \( \beta \)
  • C
    one \( \alpha \) and one \( \beta \)
  • D
    four \( \alpha \) and one \( \beta \)

Solution

A radioactive decay can form an isotope of the original nucleus with emission of one \( \alpha \) and two \( \beta \) particles.
\[ Z_{Z-2}^{A} X-{ }^{A} Y-3^{A-4} Y+\alpha \]

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