Consider Isotope I which undergoes radioactive decay to produce another radioactive nuclide that undergoes another radioactive decay until Isotope V is produced. There are two types of decay processes, one depicted by shorter arrows pointing to the right and the other depicted by longer arrows pointing to the left. Determine the identity of each species in the series by providing their isotopic symbol (^A_ZX).
