The electron emitted in beta radiation originates from

A

inner orbits of atom

B

free electron existing in nuclei

C

decay of a neutron in a nucleus

D

photon escaping from the nucleus

Text Solution

Verified by Experts

The correct Answer is:
C
During `beta-`decay, a neutron is transformed into a proton and an electron. This is why atomic number (Z= number of protons) increases by one and mass number (A= number of protons + neutrons) remains unchanged during beta decay.
