List of isotopes / atomic number 71 to atomic number 80

This article or the following section is not adequately provided with supporting documents ( e.g. individual evidence ). Information without sufficient evidence could be removed soon. Please help Wikipedia by researching the information and including good evidence.

The list of isotopes is the overview page for easy access to all elements. The structure is also explained there and the legend for the table can also be found there. Decay energies were recalculated with the given masses and the mass-energy equivalent of . ${\displaystyle \textstyle \Delta m=931{,}4940954{\frac {\mathrm {MeV} }{\mathrm {u} }}}$
