gained

released

Explanation:
Detailed explanation-1: -Energy is absorbed to break bonds, and energy is evolved as bonds are made. In some reactions the energy required to break bonds is larger than the energy evolved in making new bonds, and the net result is the absorption of energy. Hence, different types of bonds may be formed in a reaction.
Detailed explanation-2: -Breaking a bond, in isolation, never releases energy. Bonding is a stable state compared to the unbonded species, where opposite charges are closer together when bonded compared to unbonded and the whole system is at a lower (electrical) potential energy.
