All the radioactive series terminate at lead . Why?
Answers
Answer:
As the comments above indicate, the decay chains will terminate at a stable nuclei. For the series you mentioned in your question, lead has the first stable isotope.
A really useful tool for looking at different decay chains is available from Oak Ridge National Laboratory's Risk Assessment Information System.
You can pick from lots of different isotopes and see the decay chains. For example, 14256Ba gives 14258Ce as the final stable product. 146C goes to 147N, etc. Many terminate with lead, but many don't.
As for hydrogen? Keep in mind that for large nuclei, fission and other nuclear processes that decrease the number of protons are usually favored, but for small nuclei, processes that increase the number of protons are often favored (e.g., beta decay) - changing the neutron-proton ratio and generating more stable nuclides.
