Does breaking bonds require energy, release energy, or not involve energy at all?

requires energy to be absorbed into the system
no energy is involved
releases energy when broken

Breaking bonds requires energy to be absorbed into the system. This is because a bond is the result of the attraction between two atoms or molecules, and breaking this bond requires an input of energy to overcome this attraction. Therefore, breaking a bond is an endothermic process that requires energy. Conversely, the formation of a bond releases energy and is an exothermic process.
