In a radioactive decay process, the negatively charged emitted β\beta-particles are:

Options

  1. Athe electrons produced as a result of the decay of neutrons inside the nucleus
  2. Bthe electrons produced as a result of collisions between atoms.
  3. Cthe electrons orbiting around the nucleus
  4. Dthe electrons present inside the nucleus.

Correct answer

A. the electrons produced as a result of the decay of neutrons inside the nucleus

Step-by-step solution

In β−\beta^{-}-decay a neutron is transformed into a proton and an electron is emitted with the nucleus along with an antineutrino. n→p+eˉ+vˉn \rightarrow p+\bar{e}+\bar{v} where vˉ=\bar{v}= antinutrino
