the larger ones represent chloride ions. In the expanded view (b), the geometry can be seen more clearly. Note that each ion is “bonded” to all of the surrounding ions—six in this case.
所谓的bonding(键)其实就是一种连接方式,需要学习的是atom原子这样的微观粒子,通过何种方式连接成为我们眼中能看到的宏观的物质。 今天我们来讲一下三种不同的bonding---ionic 、covalent、metallic Ionic bonding(离子键):原子在得失电子后成为ion(离子),失去电子的原子成为positive ions(其整体带正电,因内部带正电...
Chemical bonds form when the total energy of the bonded atoms is lower than the total energy of the separate atoms. The form the bonding takes is determined by the electron arrangement that minimizes the energy.In some instances, electrons are shared between atoms - this is termed covalent ...
Ionic bonds form between metals and nonmetals.
Related to Ionic bonding:Chemical bonding,Metallic bonding ionic bond In sodium chloride, a sodium atom (Na) donates an electron to a chlorine atom (Cl), forming an ionic bond. ionic bond n. A chemical bond between two ions with opposite charges, characteristic of salts. Also calledelectrova...

of chlorine to gain an electron, the elements are well suited to bond with one another. This transfer of electrons results in the formation of the ionic bond holding Na+and Cl–together. Ionic bonding is very common ininorganic chemistrybut is encountered much less frequently inorganic chemistry...
