PHYSICS 7408 (PHYSICS 7408)

Two isotopes of iodine are 125 53 I and 131 53 I. Determine, for these two isotopes, the difference between the constituents of the nuclei. [1 mark] 0 1 . 2 A 131 53 I nuclide undergoes beta (β– ) decay to form a xenon nuclide. State the nucleon number of the xenon nuclide. [1 mark] 0 1 . 3 A 125 53 I nuclide decays by electron capture to form a tellurium nuclide. State two differences between the constituents of the iodine nucleus and the tellurium nucleus it decays into. [2 m...
