SUMMARY
The discussion focuses on calculating the Q-value and kinetic energy of an alpha particle during alpha decay, using the nuclear masses of the parent nucleus (Mp = 226.025 amu), daughter nucleus (Md = 222.017 amu), and alpha particle (Mα = 4.002 amu). The Q-value is determined using the formula Q = (Mp - Md - Mα) amu, resulting in a value of 5.589 MeV. Subsequently, the kinetic energy of the emitted alpha particle is calculated using the equation Q = Eα(1 + Mα/Md), yielding Eα = 5.490 MeV. The calculations are confirmed to be correct, although a suggestion is made to consider the mass of electrons for a more precise result.
