Calculate the mass defect and binding energy of lithium-7. Themass of lithium-7 is 7.016003 amu.

Calculate the nuclear binding energy in mega electronvolts (MeV) per nucleon for 244 Pu. 244Pu nuclear mass of 244.064 amu.

The isotopic mass of 21086Rn is 209.989669 amu. When thisnuclide decays by electron capture, it emits 2.368 MeV. What isthe isotopic mass of the resulting nuclide

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. (1 pm = 10⁻¹² m; mass of electron (amu) = 0.000549)   Americium-241 is widely used in smoke detectors. 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.
