1.  A table posted by C. R. Nave (2005) at the Georgia State University contains binding energy  (in MeV) information for many isotopes.  This web site is called Hyperphyscis and it contains a large amount of information dealing with many different aspects of science.   The table can be found by clicking on Tables, then Nuclear Physics, then Periodic Table.  An example of the type of information provided by C. R. Nave is shown below for education purposes only:

2.  A second table, from the Korea Atomic Energy Research Institute (2000), lists binding energies (in KeV) for numerous isotopes, and other information, and can be found at this internet Link.  Because the binding energy calculations are in KeV this table provides more significant figures of information than the above table by C. R. Nave.  An example of information provided by this web site is shown below for educational purposes only:

2-He basic

2-heliumNaturally occuring isotopes: He-3   ( 0.000137% ) He-4   ( 99.999863% ) Isotopes: He-5   He-6   He-7   He-8   He-9   He-10   For information on elements, we recommend .

3.  Found at this [Link] is a web site by Kenneth L. Barbalace that provides excellent periodic table of elements that lists the decay modes for many isotopes, including parent isotopes and decay energies.  This site does not contain information on binding energy for isotopes.   An example of information provided by this web site is shown below for educational purposes only:
