A nuclear reaction given by $_Z{X^A}\, \to {\,_{Z + 1}}{Y^A}{ + _{ - 1}}{e^0} + \bar p$ represents
$\gamma-$ decay
Fusion
Fission
$\beta-$ decay
What happens to the mass number and atomic number of an element when it emits $\gamma$-radiation?
A radioactive nucleus emits a beta particle. The parent and daughter nuclei are
Explain $\beta -$ decay and how does a radioactive nucleus emit $\beta -$ particles, even if there are no $\beta -$ particles in the nucleus ? Here why does radioactive nuclide not change during beta emission ?
$_1{H^1}{ + _1}{H^1}{ + _1}{H^2} \to X + {\;_{ + 1}}{e^0} + $energy. The emitted particle is
