In both β− and β+ decay processes, the mass number of a nucleus remains the same, whereas the atomic number Z increases by one in β− decay and decreases by one in β+ decay. Explain giving reason.
In β− decay, a β particle of zero mass and −1 charge is emitted. The decay process is shown below:
Similarly, for a β+ decay, a β particle of negligibly small and +1 charge is emitted. The decay process is shown below:
