Write a nuclear equation for these two processes

Question

When isotope 27 Al is irradiated with alpha particles the

                    13

products from each aluminum nucleus are a neutron and a nuclide that emits positrons to give the stable isotope 30 Si

                                                                              14

Write a nuclear equation for those two processes

                    

Answer 1

27        4         1         30

   Al  +    He →   n    +     P

13        2         0         15

 

 30       0      30

    P  →   e +    Si

 15       1      14
