Mass-energy relationship

Tlie kind of trcuisformation tliat will take place for any given radioactive element is a function of the type of nuclear instability as well as the mass/eiiergy relationship. Tlie nuclear instability is dependent on the ratio of neutrons to protons a different type of decay will occur to allow for a more stable daughter product. The mass/energy relationship stales tliat for any radioactive transformation(s) the laws of conservation of mass tuid tlie conservation of energy must be followed.

A. (a) Show, using the Einstein mass-energy relationship, that 1.00 AMU is equivalent to 931 Mev of energy. 

Nuclear chemistry represents a particularly simple limiting form of kinetics in which unstable nuclei decay with a constant probability during anytime interval. Its richness arises from the multiplicity of decay paths that are possible, which arise from the mass-energy relationships that determine nuclear stability. 

The equivalence of these criteria follows from Einstein s mass-energy relationship. Spontaneous transformations of one nucleus into others can occur only if the combined mass of products is less than the mass of the original nuclide. 

The energy change AE that results from a mass change in a nuclear reaction (Am) is given by the Einstein mass-energy relationship AE = c Am.

Strategy To calculate the nuclear binding energy, we first determine the difference between the mass of the nucleus and the mass of all the protons and neutrons, which gives us the mass defect. Next, we apply Einstein s mass-energy relationship [A = (Aw)c ].
