Open Question
Thorium-232 decays by a 10-step series of nuclear reactions, ultimately yielding lead-208, along with 6 α particles and 4 β particles. How much energy (in kJ/mol) is released during the overall process? The relevant masses are 232Th = 232.038 054, 208Pb = 207.976 627, electron = 0.000 548 6, and 4He = 4.002 603.
