5.1离子键与离子化合物ionic bonding and ionic compound.ppt,Ⅴ、Brittleness Ionic compounds are brittle and hard in solid state. Reason: (1) Ionic bonds are strong. (2) Strength of ionic bonds is the same in each direction in the lattice structure. In othe
2. Shattering: Ionic compounds are hard and brittle. 3. Conductivity: Ionic compounds dissociate into ions when dissolved in water. Solutions of ionic compounds and melted ionic compounds conduct electricity, but solid materials do not. 本文禁止转载或摘编 分享到: 投诉或建议 0评论 《闪耀!优俊少女...

The properties of ionic compounds shed some light on the nature of ionic bonds. Ionic solids exhibit a crystalline structure and tend to be rigid and brittle; they also tend to have high melting and boiling points, which suggests that ionic bonds are very strong. Ionic solids are also poor ...
ionic bonding(离子键)对应的化合物ionic compound(离子化合物)的结构: 这里面紫色的微粒代表cation,绿色的微粒代表anion,正负电荷相互吸引,而且引力非常强,一般情况下不容易被破坏。 这种结构有一个专属名词:lattice(晶格)。 你会发现这里面的cation...
