WebNov 27, 2016 · The actual structure doesn't differ all that much, but its mass does differ, thus its density is a little different. This is the result of the different number of neutrons that are located in the "center" of the atom. For example (the image below), carbon has three isotopes, each with a different number of neutrons. WebSo A is the mass number, which is equal to the number of protons, that's the atomic number which we symbolized by Z, plus the number of neutrons. So A is equal to Z plus N. And for protium, let's look at protium here. So in the nucleus there's only one proton and zero neutrons, so one plus zero gives us a mass number of one.
