  1. In a radioactive decay process, the negatively charged emitted β-particles are
    1. the electrons produced as a result of the decay of neutrons inside the nucleus
    2. the electrons produced as a result of collisions between atoms
    3. the electrons orbiting around the nucleus
    4. the electrons present inside the nucleus
Correct Option: A

​In beta minus decay (β–), a neutron is transformed into a proton, and an electron is emitted from the nucleus along with antineutrino.
