79. The lines that lead toward the lower left are alpha decays, involving an atomic number change of Z α = – 2 and a mass number change of A = – 4. The short horizontal lines toward the right are beta decays (involving electrons, not positrons) in which case A stays the same but the change in atomic number is Z β = +1. Fig. 42-20 shows three alpha decays and two beta decays; thus,
