An element X decays, first by positron emission and then two α-particles are emitted in successive radioactive decay. If the product nucleus has a mass number 229 and atomic number 89, the mass number of atomic number of element X are.
In a radioactive decay chain, 232 Th 90 nucleus decays to 212 Pb 82 nucleus. Let Nalpha and Nbeta be the number of alpha and beta particles, respectively , emitted in this decay process.
