揭示格鲁波尔:通过构建块方法预测宏分子的电和静电性质

Physical models representing molecular architectures of chemical compounds play essential roles in understanding chemistry. The use of molecular models makes it easier to visualize the structures and shapes of atoms and molecules.

VSEPR Theory for Determination of Electron Pair Geometries

Overview of VSEPR Theory

The VSEPR theory can be used to determine the electron pair geometries and molecular structures as follows:

A neutral atom consists of a positively charged nucleus surrounded by a negatively charged electron cloud. When placed in an external electric field, the external electric force pulls the electrons and nucleus apart, opposite to the intrinsic attraction between the nucleus and the electrons. The opposing forces balance each other with a slight shift between the center of masses of the nucleus and the electron cloud, resulting in a polarized atom. On the other hand, a few molecules, like water,...
