Question

If the nucleons of a nucleus are separated far apart from each other, the sum of masses of all these nucleons is larger than the mass of the nucleus. Where does this mass difference come from? Calculate the energy released if 238U nucleus emits an
alpha particle. Given Atomic mass of 238U = 238.0508 u

Answer 1

according to Dalton's atomic theory atomic mass unit equal to one by two well the mass of carbon does one atomic mass unit is defined as exactly 112th the mass of an atom of carbon
