The model used to determine the molecular shape is referred to as the Valence Shell Electron Pair Repulsion model, or VSEPR model. This model is based on an arrangement that minimizes therepulsionof shared and unshared electron pairs around the central atom. 用来确定分子形状的模型称为,价层电子...
而VSEPR模型是一种常用的判断分子形状的方法。本文将介绍VSEPR模型的基本原理、应用方法和一些常见分子的形状。 一、VSEPR模型的基本原理 VSEPR模型全称为Valence Shell Electron Pair Repulsion model,即价层电子对斥力模型。它基于一个简单的假设:电子对在空间中的排布会尽量远离彼此,以减少它们之间的斥力。根据这个原理...
