Determine the number of neutrons in the nucleus of the resultant nuclide of Y when a nuclear reaction involves the hypothetical element X, which has an atomic number of 168, as a reactant. The 353X nuclide reacts with 3 neutrons yielding a nuclide of element Y along with, altogether, 2 beta particles, 3 neutrons, 3 alpha particles, 3 positrons, and 5 gamma rays.
