37Ca and 53Fe have the same decay mode.
What are the three common modes of radioactive decay?
Three of the most common types of decay are alpha decay (α-decay), beta decay (β-decay), and gamma decay (γ-decay), all of which involve emitting one or more particles.
Which isotopes are most likely to decay?
The most likely mode of decay for a neutron-rich nucleus is one that converts a neutron into a proton. Every neutron-rich radioactive isotope with an atomic number smaller than 83 decays by electron emission. C, 32P, and 35S, for example, are all neutron-rich nuclei that decay by the emission of an electron.
