MCQ
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
  • ✓
    the electrons produced as a result of the decay of neautrons inside the nucleus
  • D
    the electrons present inside the nucleus
✓

Answer

Correct option: C.
the electrons produced as a result of the decay of neautrons inside the nucleus
c
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
