WebbThe spontaneous decay or breakdown of an atomic nucleus is known as Radioactive Decay. This decay in a nucleus causes the release of energy and matter from the nucleus. The most common forms of Radioactive decay are: Alpha Decay (Helium nucleus is emitted) Beta Decay (Electrons are emitted) Gamma Decay (High energy photons are … WebbThe basic decay processes are n → p + e - + ν° plus a delayed γ, the two silver isotopes decay to the stable elements 110 Cd and 108 Cd. A chart summarizing the information about the neutron source and silver isotopes is included at the end of this write-up and can be used for an OHP transparency. Setting it up:
WebbRadioactive isotopes are isotopes that undergo spontaneous nuclear decay in other to become a stable isotope (and get closer to the belt of stability). During nuclear decay, …
