Calculate the neutron:proton ratio.
For 48K it has 29N and 19P N/P = 1.5
79Br has 44N and 35P with N/P = 1.26
32Ar has 14N and 18 P with N/P = 0.77
Here is a graph of #neutrons vs #protons.
32Ar is far below the band of stability.
48K is above
79Br look relatively close; I think that is the stable one of the three listed.
which nuclides would you expect to be stable?
a) 48K
b)79Br
c)Argon-32
