Question

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

• A. the electrons orbiting around the nucleus
• B. the electrons present inside the nucleus
• C. the electrons produced as a result of the decay of neutrons inside the nucleus
• D. the electrons produced as a result of collisions between atoms

Answer 1

The correct option is C the electrons produced as a result of the decay of neutrons inside the nucleus

In radioactive decay process, the negatively charged emitted $\beta$ particles are the electrons produces as a result of the decay of neutrons inside the nucleus.

In $\beta$-decay a neutron in the nucleus decays into a proton, a fast moving electron ($\beta$ particle) and an anti-neutrino$\left(v_e\right)$

$n⟶p+e^{-}+v_e$
