- Write a balanced equation for each of the following nuclear reactions: (a) bismuth-212 decays into polonium-212. (b) beryllium-8 and a positron are produced by the decay of an unstable nucleus. (c) neptunium-239 forms from the reaction of uranium-238 with a neutron and then spontaneously converts into plutonium-239. (d) strontium-90 decays into yttrium-90arrow_forwardPlutonium was detected in trace amounts in natural uranium deposits by Glenn Seaborg and his associates in 1941. They proposed that the source of this 239Pu was the capture of neutrons by 238U nuclei. Why is this plutonium not likely to have been trapped at the time the solar system formed 4.7109 years ago?arrow_forward
