Uncategorized: Practice Problem & Solution

71. A nuclear reaction given by $_{Z}X^{A} \rightarrow _{Z+1}Y^{A} + _{-1}e^{0} + \bar{\nu}$ represents: (2003)
$\beta$-decay
$\gamma$-decay
Fusion
Fission

Solution Explained:

To solve this problem, we apply the core principles of Uncategorized. Understanding the underlying formula is key to arriving at the correct answer below:

The emission of an electron ($_{-1}e^{0}$) along with an antineutrino ($\bar{\nu}$), resulting in an increase of atomic number by 1 while the mass number remains unchanged, is the characteristic of $\beta$-decay.
