In radioactive decay process, the negatively charged emitted beta particles are:
-
the electrons present inside the nucleus
-
the electrons produced as a result of the decay of neutrons inside the nucleus
-
the electrons produced as a result of collisions between atoms
-
the electrons produced as a result of collisions between atoms
B.
the electrons produced as a result of the decay of neutrons inside the nucleus
Beta decay can involve the emission of either electrons or positirons. The electrons or positrons emitted in a beta-decay do not exist inside the nucleus. They are only createdat the time of emission, just as photons are created when an atom makes a transition from higher to a lower energy state.
In negative Beta decay a neutron in the nucleus is transformed into a proton, an electron and an antineutrino. Hence, in radioactive decay process, the negatively charged emitted beta process are the electrons produced as a result of the decay of neutrons present inside the nucleus.
