WebTo get the abundance of each isotope, you could use a tool called a mass spectrometer. Basically how it works is that you have a stream of ionized atoms of one element. Then, you use a magnet to try and kick them out of their path. The ones that are the heaviest will be pushed less, and the lighter ones will be pushed more. WebStable nuclides are nuclides that are not radioactive and so (unlike radionuclides) do not spontaneously undergo radioactive decay. When such nuclides are referred to in relation to specific elements, they are usually termed stable isotopes..
