Answer: 1) The nuclide formed from the alpha decay of
is 
2) The nuclide formed from the beta-minus decay of
is 
Explanation:
1) For alpha-decay
In this process, alpha particle is released.
Equation follows:

The nuclide formed is 
2) For beta-minus decay
In this process, a neutron is converted into a proton and an electron.
Equation follows:

The nuclide formed is
