I choose the most abundant isotope, #""^120Sn# ; note that tin has many isotopes.

Explanation:

Now all tin isotopes have 50 nuclear protons, and 50 electrons; we know this from the atomic number of #Sn,# #Z=50#.

#""^120Sn# has 70 neutrons, 70 massive, neutrally charged nuclear particles. It is approx. 30% abundant.
