Chart of Nuclides: Xe128 and Processes for X+-5

The above link is what I've done for this question.

The problem was that we had to choose a mass number X on the chart of the nuclides and then had to show the s,r and p processes on the chart for X+-5.

So I chose Xe128 and have done X+-5

However, Sn 124 is a magic number and I'm not sure about this??
I also wanted to check if everything else is ok and is Te123 just an s process?

Thanks for any help

Nevermind I found a site that explains how to do this so I found that Te123 is s-process and so is Sn124.
