  10. The most stable isotope of Technetium has 43 protons and 55 neutrons, neither
  11. of which complete shells, and neither of which pair spins.  Adding and
  12. subtracting neutrons puts Technetium father above or below the belt of
  13. stability.  Technetium was doomed, therefore, to eternal radioactivity.
