(a) Energy is required to separate a nucleus into its constituent nucleons, as the drawing indicates; this energy is the total binding energy of the nucleus. In a similar way one can speak of the energy that binds a single nucleon to the remainder of the nucleus. For example, separating nitrogen 7N15 into 7N¹4 and a neutron takes energy equal to the binding energy of the neutron. Find the energy (in MeV) that binds the neutron to the 7N¹5 nucleus by considering the mass of 7N¹4 (atomic mass = 14.003074 u) and the mass of on¹ (atomic mass = 1.008665 u), as compared to the mass of 7N15 (atomic mass = 15.000108 u). (b) Similarly, one can speak of the energy that binds a single proton to the 7N15 nucleus. Following the procedure outlined in part (a), determine the energy (in MeV) that binds the proton (atomic mass= 1.007825 u) to the 7N¹5 nucleus. The atomic mass of carbon 6C¹4 is 14.003242 u. (c) Which nucleon is more tightly bound, the neutron or the proton? + + Binding energy (greater)…
A positron and an electron annihilate each other upon colliding, thereby producing energy in the form of two gamma rays. Assuming that both gamma rays have the same energy (since both particles have the same mass), calculate the wavelength of the electromagnetic radiation used in pm.

Calculate the amount of americium-241 consumed in a smoke detector (initially containing 5.00 µg of Am), in micrograms, that has been used for one year if the half-life is 433 years.
Find the attachment.
The naturally occurring radioactive isotope 232Th does not make good fission fuel, because it has an even number of neutrons; however, it can be bred into a suitable fuel (much as 238U is bred into 239P ). Confirm that the final nucleus has an odd number of neutrons, making it a better fission fuel.
Each of the following nuclei undergoes either beta decay or positron emission. Predict the type of emission for each: (a) tritium, 3 1H, (b) 89 38Sr, (c) iodine-120, (d) silver-102.
Calculate the binding energy per nucleon (in J) for 108 and 118. The atomic masses are 10.012937 u for 108, and 11.009306 u for 113. (Enter unrounded values. Assume that the mass of H = 1.007825 u, mp = 1.007275 u, mn = 1.008666 u, and m = 0.000549 u, respectively.) 10B -1.824e-14 118 -2.3920-14 XJ/nucleon XJ/nucleon Need Help?
