Question

A nuclear reaction is given by,
ZXA → Z+1YA +–1e0+$\bar v$ represents

• A. $\beta$-decay
• B. $\gamma$-decay
• C. fusion
• D. fission

Answer 1

Answer: (A)

$\beta$-decay

Answer 2

In a β-decay, a nucleus undergoes a transformation in which a neutron is converted into a proton, an electron (also known as a β-minus particle, denoted as -1e0), and an antineutrino (v). This results in the increase of the atomic number (Z) by one unit (hence the "+1" in Z + 1YA), while the mass number (A) remains the same.
