What is meant by bond energy, and how does it affect bond strength?

Bond energy (or bond dissociation energy) is the amount of energy required to break one mole of bonds in a molecule in the gas phase. It measures the strength of a chemical bond. The higher the bond energy, the stronger the bond, as more energy is required to break it. Bond energy is typically higher in shorter and stronger bonds, such as in the case of triple bonds (e.g., in nitrogen gas, N≡N), and lower in longer, weaker bonds (e.g., in single bonds like in hydrogen gas, H-H).
