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...
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和anion很多,而且排列还挺有规则的,但这也只是这个ionic compound的结...
This results in the ions arranging themselves into a tightly bound, three-dimensional lattice structure. Sodium chloride, for example, consists of a regular arrangement of equal numbers of Na+ cations and Cl– anions (Figure 2).Figure 2. The atoms in sodium chloride (common table salt) are ...
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
The secondary school learners see ionic bonding as consisting of attraction of oppositely charged species that arise from the transfer of electrons driven by the desire of atoms to obtain an octet of electrons. The undergraduates see the lattice structure as a key component of ionic substances and...

The ionic conduction in solid-state materials is defined as the tendency of materials toward ions movements from one site to another. This happens particularly within the defects of thecrystal lattice. The termionic bondingis an important factor of many compounds which allows ionic diffusion. In ot...
