The valence-shell electron-pair repulsion (VSEPR) model allows us to predict which of the possible structures is actually observed in most cases. It is based on the assumption that pairs of electrons occupy space, and the lowest-energy structure is the one that minimizes electron pair–electron pair repulsions.

2024年11月14日 · 价层电子对互斥理论 （英语： Valence Shell Electron Pair Repulsion，简称为 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。 价层电子对互斥理论 也称为吉莱斯皮-尼霍姆理论，因为该理论的两位主要创始人分别是 罗纳德·吉莱斯皮 和 罗纳德·尼霍姆。 1939 年，日本化学家 槌田·龙太郎 （Ryutaro …

Building of and describing HBr using VSEPR Theory as well as molecular models: ball and stick, space filling, relative atomic size.

The words that make up the initialism “VSEPR”—valence shell electron-pair repulsion —describe the concept of the theory very well. The main concept of the theory is that pairs of electrons, both bonding and non-bonding, will repel one another and maximize the distance between themselves around an atom. This can be used to predict geometric

價殼層電子對互斥理論 （英語： Valence Shell Electron Pair Repulsion，簡稱為 VSEPR），是一個用來預測單個共價分子形態的 化學 模型。 理論通過計算中心 原子 的價層電子數和 配位數 來預測 分子的幾何構型，並構建一個合理的 路易斯結構式 來表示分子中所有鍵和 孤對電子 的位置。 價殼層電子對互斥理論 也稱為吉萊斯皮-尼霍姆理論，因為該理論的兩位主要創始人分別是 羅納德·吉萊斯皮 和 羅納德·尼霍姆。 1939 年，日本化學家 槌田·龍太郎 （Ryutaro Tsuchida）首先 …

The valence shell electron pair repulsion (VSEPR) theory is a model used to predict 3-D molecular geometry based on the number of valence shell electron bond pairs among the atoms in a molecule or ion. This model assumes that electron pairs will arrange themselves to minimize repulsion effects from one another.

The valence-shell electron-pair repulsion (VSEPR) model provides a simple method for predicting the shapes of such species. The Cambridge Structural Database contains a wealth of diverse molecular geometries, and provides the ability to visualise and manipulate molecules in …

2024年8月23日 · The valence shell electron pair repulsion (VSEPR) theory is based on the principle that electron groups such as single bonds, double bonds, triple bonds, or single electrons repel one another through Coulombic forces

What Is VSEPR? The Valence Shell Electron Pair Repulsion (VSEPR) model: is based on the number of regions of high electron density around a central atom. can be used to predict structures of molecules or ions that contain only non-metals by minimizing the electrostatic repulsion between the regions of high electron density.
