WebNov 28, 2024 · Why are some isotopes stable and others not? The answer is the ratio of protons ( positive charges that push each other apart and cause the break up of the nucleus) and neutrons that are attracted to the charged protons and hold the nucleus together. In small atoms a 1 :1 ratio of protons to neutrons is the most stable. WebAug 6, 2024 · A particular element can have more than one stable isotope. For some elements such as Uranium, all isotopes are unstable.
