Why is Energy Released During Bond Formation?

Click For Summary
SUMMARY

Energy is released during bond formation due to the transition from high-energy, unstable atoms to low-energy, stable molecules. The stability of a molecule is inversely proportional to its energy; as atoms bond, they release excess energy, which manifests as exothermic heat. This process can be likened to a classroom where lower energy levels lead to greater stability. The conservation of energy principle explains that the energy difference between the unstable atoms and the stable molecules is liberated during bond formation.

please can anyone explain me in simple words why energy is released when bonds are formed?

Atoms independently are generally not stable, so they tend to exist in form of molecules. Stability is proportional to energy. High energy is attributed to less stability as compared to low stability.

Think of it as a classroom, where discipline (stability) of the class is dependent upon the energy of the students. Obviously, if the children are shouting (low energy) class' decorum is maintained, if they start howling (high energy) the class becomes unstable.

Now, molecules are formed when the bonds are made. Now the molecule formed is stable as opposed to independent atom, so by conservation of energy, the excess energy difference is liberated as exothermic heat, some work, etc.
