1940年美国的 Sidgwick等人提出了价层电子对互斥理论(valence shell electron pair repulsiontheory),简称 VSEPR法。对于 AX。型分子或离子,其价层电子对指的是中心原子形成σ键的电子对和孤对电子对,其数目等于X原子数n与孤对电子对数之和。该理论认为,AX。型分子或离子的几何构型,主要决定于中心原子的价层电子...
阅读下面的材料并思考价层电子对互斥理论(Valence Shell ElectronPair Repulsion Theory)适用于主族元素间形成的AB_n 型分子或离子。该理论认为,一个共价分子或离子中,中心原子A周围所配置的原子B(配位原子)的立体构型,主要决定于中心原子的价电子层中各电子对间的相互排斥作用。这些电子对在中心原子周围按尽可能互相...

1) The electron pairs in the valence shell around the central atom of a molecule repel each other and tend to orient in space so as to minimize the repulsions and maximize the distance between them.2) There are two types of valence shell electron pairs viz., i) Bond pairs and ii) ...

For example, the shell structure of heavy atoms is obvious when plotting ELF against the radial distance from the nucleus. When applied to molecules, an analysis of the ELF shows a clear separation between the core and valence electron, and also shows covalent bonds and lone pairs, in what ...
