Neutrons The atomic number is the number of protons in an atom, and isotopes have the same atomic number but differ in the number of neutrons. Unstable isotopesdecay through various radioactive decay pathways, most commonly alpha decay, beta decay, or electron capture. If a neutral atom has 10 protons, it must have 10 electrons. The number of neutrons is calculated by subtracting the mass number with the atomic number. Of these, 90Sris a trace radioisotope, decaying by beta decay with a half-life of 28.90years.. 88Sr is the most common isotope, having a natural abundance of approximately 82%.
