Default Re: Aren't The Nucleon Number And The Mass Number The Same?

Both Protons and Neutron ares are nucleons. Atomic number is how many protons you have, and nucleon number is the total number of protons and neutrons. That means your equation doesn't work.

The point of the exercise may be to check that you know that nucleon count = atomic mass. (Although this isn't technically true due to reasons, at that carbon end of things it's close enough.)
