13.Nuclei
easy
In a radioactive decay process , the negatively charged emitted $\beta -$ particles are
A
the electrons orbiting around the nucleus
B
the electrons produced as a result of collisions between atoms
C
the electrons produced as a result of the decay of neautrons inside the nucleus
D
the electrons present inside the nucleus
(AIPMT-2007)
Solution
In beta minus decay $\left(\beta^{-}\right),$ a neutron is transformed into a proton and an electron is emitted with the nucleus along with an antineutrino.
$n \rightarrow p+e^{-}+\bar{v}$
where $\bar{v}$ is the antineutrino
