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. Web1, 3, & 6. Each isotope has a half-life that is different from the half-life of other isotopes.
