उत्तर
A radioactive nucleus containing 128 nucleons emits a β-particle. After β- emission the number of nucleons present in the nucleus will be 128.
Explanation:
A neutron undergoes β-decay, converting it into a proton and releasing a β-particle. As a result, the mass number stays constant while the atomic number increases by 1. Therefore, there will still be 128 nucleons (the mass number).
