Detailed explanation-1: -In the decay process, this excess mass is converted into energy and appears in the form of kinetic energy in the daughter nucleus and the alpha particle.
Detailed explanation-2: -Alpha decay or -decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and thereby transforms or ‘decays’ into a different atomic nucleus, with a mass number that is reduced by four and an atomic number that is reduced by two.
Detailed explanation-3: -Answer and Explanation: During alpha decay, the parent nucleus loses 2 protons and 2 neutrons. As a result, the daughter nucleus has 2 fewer protons and 2 fewer neutrons than the parent nucleus. The atomic number, which is equal to the number of protons in the nucleus, gets reduced by a 2 as a result of this decay.
