2.1: Decay Data

I would just like to ask about the binding energy of 4-Be-5.

Binding Energy: -768.000 + 3996.000 keV

I would like to know why this particular binding energy is "-" (ie, negative value)?

 The data for Be-5 is the value from systematics ( noted by a # at the end of
number). There may be no observed data.
 For more information, please refer to the source of data
