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

Once the compounds have been dissolved in water, they can be tested to see whether they convey electricity. Covalent bonds will not convey electricity. Dissolved ionic compounds will convey electricity. References Science Spot: Bonding Basics 2010 ...
We report a computational study on the structures and bonding of a charged molecular alloy D 2h [Pd2As14]4− (1), as well as a model D 2h [Au2Sb14]4− (2) cluster. Our effort makes use of an array of quantum chemistry tools: canonical molecular orbital analysis, adaptive natural...
The strength of chemical bonds varies considerably; there are “strong bonds” such as covalent or ionic bonds and “weak bonds” such as dipole–dipole interactions, the London dispersion force, and hydrogen bonding. There is, however, no sharp distinction between “strong” and “weak” bonds...
