What are the numbers of the subatomic particles in tin?

Answer 1

Olivia Anton

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

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.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
