In chemistry its often said that energy must be added to system to break atomic bonds and conversely when atoms bond energy is released. I can picture why it takes energy to break a bond, for instance to ionize a hydrogen atom you have to exert a force on the electron to overcome the electrostatic attraction of the electron for the proton. I don't however see how that electron bonding to the proton to form a netral hydrogen atom would release energy.
