Binding Energy

  1. Nov 7, 2004 #1
    Hey Everyone,
    This is a quick question.. is binding energy positive or negative? I'm pretty confused now, because in some places the definition was:

    The energy released when the nucleus of an atom is formed by combining neutrons and protons.

    And in other places:

    the energy required to decompose a nucleus into its component nucleons

    Dont they both imply different signs? Please clarify..
    Thank you..

    Binding energies are taken as positive, so use either definition and ignore negative signs.
