bond strength

Bond strength refers to the amount of energy required to break a chemical bond between two atoms. It indicates how tightly the atoms are held together within a molecule. Stronger bonds require more energy to break, making the substance more stable, while weaker bonds break more easily, leading to lower stability. Bond strength influences the physical and chemical properties of materials, such as their melting points, reactivity, and durability. Essentially, it reflects the level of attraction between atoms, determining how much effort is needed to separate them.
