WebOct 22, 2024 · Definition When a bond is formed between two atoms, energy is released. The same amount of energy is absorbed when the bond is broken to form neutral atoms. So, ‘’the bond energy is the average amount of energy required to break all bonds of a particular type in one mole of the substance’’. Explanation WebA diatomic molecule has one normal mode of vibration, since it can only stretch or compress the single bond. A molecular vibration is excited when the molecule absorbs energy, ΔE, corresponding to the vibration's frequency, ν, according to the relation Δ E = hν, where h is Planck's constant. earth zero
