What is alpha and beta decay?
Atomic and mass numbers fall as a result of alpha decay, which releases an alpha particle made up of two protons and two neutrons. In heavy nuclei, it is frequently used to attain a more stable structure.
In contrast, beta decay results in the emission of a beta particle and the conversion of a neutron into a proton or vice versa. This procedure aids in adjusting nuclei's proton-neutron ratio.
