WebJan 14, 2024 · Isotope is used to specify a nuclide (using the new vocab word right away!) of a specific element. For example, if we’re only talking about uranium, then we can talk about isotopes of uranium. The isotope uranium-235 has 3 fewer neutrons than uranium-238. U-235 and U-238 are isotopes of uranium, but they’re not the only isotopes. Not … WebSince protons and neutrons have roughly the same mass, the more common version of carbon is called carbon-12 (6 protons + 6 neutrons). The heavier isotope is called carbon-14 (6 protons + 8 neutrons). But when you look up the mass of carbon on the periodic table, it says that the mass is 12.011 atomic mass units (amu).

Determines which isotope you have

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. WebAn atom of an element with a different number of neutrons is an isotope of that element. For example, the isotope carbon-12 contains 6 neutrons in its nucleus, while the isotope carbon-13 has 7 neutrons. Some isotopes are radioactive, which means they are unstable and likely to decay.
