Bond formation is associated with:
Correct answer: A. Release of energy
- A. Release of energy
- B. Absorption of energy
- C. No change in energy
- D. Sharing of nucleus
Explanation
During bond formation, energy is released as atoms achieve a more stable, lower-energy state. This is a characteristic of exothermic reactions. Therefore, the correct answer is the release of energy. The other options are incorrect because energy absorption is associated with bond breaking, no change in energy is not possible during bond formation, and the sharing of the nucleus is a misunderstanding of chemical bonding, which involves electron interactions.

About Thermochemistry and Energetics of Chemical Reactions
Thermochemistry measures energy changes in chemical reactions and distinguishes exothermic from endothermic processes. Work covers systems, surroundings and state functions, internal energy, the first law of thermodynamics, enthalpy and Hess's law, including the sign conventions used when heat enters or leaves a system.
