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 bonding - Ionic, Covalent, Polar: This section treats several aspects of molecular structure that are of more specialized interest and shows how particular classes of compounds are described. Molecular orbital theory will be used as a framework

Chemical bonding, any of the interactions that account for the association of atoms into molecules, ions, crystals, and other species. When atoms approach one another, their electrons interact and tend to distribute themselves in space so that the total
This chapter covers chemical bonding between atoms and ions and how this affects the chemical properties of the elements. Which elements form ions and the typical charges on the ions are explained. Ionic bonding and covalent bonding are compared in terms of the octet rule and valence bond theory...
