Explain, with
the help of a nuclear reaction in each of the following cases, how the
neutron to proton ratio changes during (i) alpha- decay (ii) beta-decay?

Expert Answer
(i)
Neutron to proton ratio before 
- decay = 
Neutron to proton ratio after - decay = 
As 
Thus, the neutron to proton ratio increases in an -decay.
(ii)
Neutron to proton ratio before 
-decay = 
Neutron to proton ratio after -decay = 
As 
Thus the neutron to proton ration decreases in a -decay
