identify the nuclide produced when uranium-238 decays by alpha emission: 238 92u→42he+?



we can write the nuclear decay equation and balance it to identify the missing nuclide
23892U→42He+?
 The MISSING NUCLIDE MOST HAVE A CHARGE OF 90 and mass of 234, because and mass must be balanced o both sides

23892U→42He+ 23490U
