Introductory nuclear physics

Hi.

Can anybody help me with this exercise in Introductory Nuclear Physics:

One of the magic numbers for nuclei is 28. How many stable isotopes exist with N = 28. (N being the number of neutrons)

I have no idea on how to solve this.

Thanks.

I think you are just supposed to look up various possibilities and see if they are stable.

Start with Z a low number <28 and go to Z a high number > 28 and look up the stable isotopes of each to see if the isotope with N=28 is stable.

Ok, thanks. That's a pretty stupid exercise. I can't believe it was on last years exam.
