- Francium was discovered as a minor decay product of actinium-227. Write the nuclear equation for the decay of actinium-227 by alpha emission.arrow_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_forwardFor each pair of elements listed, predict which one has more stable isotopes. (a) Ni or Cu (b) Se or Sb (c) Cd or Auarrow_forward
