WebA less stable form of iodine also has 53 protons (this is what makes it behave chemically as iodine) but four extra neutrons, for a total atomic weight of 131 (53 protons and 78 neutrons). With "too many" neutrons in its nucleus, it is unstable and radioactive, with a half-life of eight days. WebThis isotope of iodine has 78 neutrons in its nucleus, while the only stable nuclide, 127 I, has 74. On decaying, 131 I most often (89% of the time) expends its 971 keV of decay energy by transforming into stable xenon-131 in two steps, with gamma decay following rapidly after beta decay: sims 4 70s clothes
