ionic bond

The problem of whether the effect between particles is destroyed or not is analyzed in this paper, when ionic crystals, molecular atomic crystals and metallic crystals are melting, boiling or dissolving in water. That is the problem whether the chemistry bond is broken or not.

分析了离子晶体、原子晶体、分子晶体和金属晶体在熔化、沸腾以及溶于水时，微粒的相互作用是否破坏，即化学键是否断裂的问题。
