The chart below shows a radioactive decay chart for Uranium-238. Through a combination of alpha- and beta-decay, radiation is released and the isotope is transmuted into a new element. For some isotopes, only one mode of decay is possible (and there is only one arrow leading from the isotope), while some isotopes allow two different decay modes (shown with two arrows leading from the isotope. The end of the process is the stable isotope of Lead-206. Some of the isotopes are relatively less stable and decay more quickly than others. Can you fill in the chart below to show a realistic decay chain leading from Uranium-238 to Lead-206?
