Neutrons in Silver: The atomic mass number of silver is 108 and has the Atomic Number of 47. So, if we know the atomic number of an element then we also know how many protons in an element. Adding one proton from an atom of Gold creates an atom of Mercury (Mercury has the Atomic number 80 therefore the number of protons =80.). For a single atom of an element, this would be a whole number, adding the number of protons, neutrons, and electrons together for the atom. Neutron activation is the process in which neutron radiation induces radioactivity in materials, and occurs when atomic nuclei capture free neutrons, becoming heavier and entering excited states.The excited nucleus decays immediately by emitting gamma rays, or particles such as beta particles, alpha particles, fission products, and neutrons (in nuclear fission). Number of Neutrons = Mass Number - Atomic Number.
