How many neutrons in the iron nucleus?

Answer 1

Ellie Andrews

You haven't specified the isotope.

#""^56Fe# is approx. 95% abundant. Because it is an iron isotope, we know that there are 26 protons in the element's nucleus (how do we know this?). Because it is the #""^56Fe# isotope, there must be #56-26=30" neutrons"# in this nucleus.

And thus there are #26+30# nucleons, massive nuclear particles present in the nucleus. Capisce?

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.
