A single 212 Po nucleus, initially at rest, emits an alpha particle as it decays into a 208 Pb nucleus. There are no other decay products, and the kinetic energy of the alpha particle is measured to be 1.407 x 10-12 J. The mass of an alpha particle is 4.0026 u. The mass of a 208 Pb nucleus is 207.98 u. The speed of light is 2.998 x 109 m/s. What is the total amount of nuclear potential energy APEmuclear, in joules, that was released in this process? APEuclear = 208 What is the difference Am between the original mass of the 212 Po nucleus and the total mass of the fragments (Pb nucleus alpha particle) after the decay?
