Electrons and Energy

  1. Apr 19, 2014 #1
    Why do atoms gain energy when they lose electrons, and why do they lose energy when they gain electrons.

    The only explanation I found (for the first question) raises more questions. The explanation was: it takes energy to remove an electron from an atom, and atoms gain that energy. I can understand why it takes energy to remove an electron from an atom, but why does the atom gain that energy?
