In a radioactive decay process, the negatively charged emitted β- particles are
Options
(a) the electrons produced as a result of the decay of neutrons inside the nucleus
(b) the electrons produced as a result of collisions between atoms
(c) the electrons orbiting around the nucleus
(d) the electrons present inside the nucleus
Correct Answer:
the electrons produced as a result of the decay of neutrons inside the nucleus
Explanation:
In beta minus decay (β⁻), a neutron is transformed into a proton, and an electronis emitted from the nucleus along with antineutrino.
n = p + e⁻ + v⁻
