Consider 100 g of 252Fm, which decays in a sequenceof fi ve decays to eventually reach 232Th. (a) Howmuch of the original sample is 252Fm, and how muchis 248Cf after one day? (b) After one month? (c) Explainwhy it is mostly curium after 5 years. (d) Whatisotope is it mostly after 100 years? (e) Approximatehow much time it will take for the sample to be mostlythorium.
