In alpha decay, shown in Fig. 3-3, the nucleus emits a 4 He nucleus, an alpha particle. Alpha decay occurs most often in massive nuclei that have too large a proton to neutron ratio.An alpha particle, with its two protons and two neutrons, is a very stable configuration of particles.n alpha decay, the atomic number changes, so the original (or parent) atoms and the decay-product (or daughter) atoms are different elements and therefore have different chemical properties.
