56. Assuming the neutrino has negligible mass, then mc m c e 22 =− mm Ti V bg . Now, since Vanadium has 23 electrons (see Appendix F and/or G) and Titanium has 22 electrons, we can add and subtract 22 m e to the above expression and obtain m m ee 2 22 23 =+ = Ti V Ti V b g We note that our final expression for mc 2 involves the atomic masses, and that this assumes (due to the way they are usually tabulated) the atoms are in the ground states (which is certainly not the case here, as we discuss below). The question now is: do we set Q = – mc 2 as in Sample Problem 42-7? The answer is “no.” The atom is left in an
