WebbIsotopes can be stable or unstable. Stable ones and unstable ones with a long half-life can be found in nature. In a process known as disintegration, unstable isotopes break up into smaller particles and residual energy. You can distinguish between an element and its isotopes by comparing its mass number and atomic number. WebbDuring the disintegration, radioactive isotopes emit alpha or beta particles and sometimes also gamma rays. The so-called stable isotopes are nuclei that do not appear to decay to other isotopes on geologic timescales, but may themselves be produced by the decay of radioactive isotopes. toy indians
