Cobalt-60. Write the balanced nuclear equation for the decay of Ag-112. All of the remaining radioactive isotopes have half-lives that are less than 60 hours and the majority of these have half-lives that are less than 30 seconds. In the presence of a static field of a p-n structure, the charges flow in one direction, resulting in an electric current. The amount of power generated by the converter depends on the thickness of the nickel foil and the converter itself, because both affect how many beta particles are absorbed. Show work in detail.

The decay is initially to a nuclear excited state of Nickel-60 from which it emits either one or two gamma ray photons to reach the ground state of the Nickel isotope. Plutonium-238 generates significant heat through its radioactive decay process, which makes it useful as a heat source for sensitive electrical components in satellites, as a well as a power source (for example, battery power) for satellites. The space industry would also greatly benefit from compact nuclear batteries. [7] It has the highest ratio of protons to neutrons (proton excess) of any known doubly magic nuclide.[8]. . But inside the nucleus, the nucleons are bound to one another by the strong nuclear force, so you also get quantized energy levels for that smaller system.
