WebNuclear energy is released by three exoenergetic (or exothermic) processes: Radioactive decay, where a neutron or proton in the radioactive nucleus decays spontaneously by emitting either particles, electromagnetic radiation (gamma rays), or both. Note that for radioactive decay, it is not strictly necessary for the binding energy to increase. WebWrite a nuclear equation for the alpha decay of Polonium-211. 2.
