The "AXE method" of electron counting is commonly used when applying the VSEPR theory. The electron pairs around a central atom are represented by a formula AX m E n, where A represents the central atom and always has an implied subscript one. Each X …

价层电子对互斥理论 (英文VSEPR)，是一个用来预测单个 共价 分子形态的化学模型。 理论通过 计算中心 原子的价层电子数和 配位数 来预测分子的几何构型，并构建一个合理的 路易斯结构式 来表示分子中所有键和孤对电子的位置。 同时，也是一种较简便的判断共价分子 几何形状 的方法，该理论紧紧抓住中心 原子价 层电子对数目这一关键因素，运用分子的几何构型取决于价层电子对数目这一假设，成功的解释并推测了许多简单分子的几何形状．. 价层电子对互斥理论常用AXE …

In the VSEPR model, the molecule or polyatomic ion is given an AX m E n designation, where A is the central atom, X is a bonded atom, E is a nonbonding valence electron group (usually a lone pair of electrons), and m and n are integers. Each group around the central atom is designated as a bonding pair (BP) or lone (nonbonding) pair (LP).

VSEPR stands for valence shell electron pair repulsion. Valence shell electrons are on the outer part of an atom. These electrons can participate in bonding (bonding pairs) or act as non-bonding electrons (lone pairs). These bonding and lone pairs electrons repel each other.

Valence shell electron pair repulsion (VSEPR) theory is a model in chemistry used to predict the shape of individual molecules based upon the extent of electron-pair electrostatic repulsion. It is also named Gillespie-Nyholm* theory after its two main developers. The acronym "VSEPR" is pronounced "vesper" for ease of pronunciation.
