48 Predicting Molecular Shapes: VSEPR Model (M9Q1) - Unizin
This section explores how we predict the molecular and electron-pair shapes of molecules using the VSEPR (Valence Shell Electron Pair Repulsion) theory. We will first go over what VSEPR theory is and how it defines an electron-pair geometry and a molecular geometry.
VSEPR Theory: Explanation, Chart, and Examples - Chemistry Learner
Predicting the Molecular Geometry. We can now use the VSEPR theory to predict the molecular geometry of compounds. We proceed through the following steps: Draw the Lewis structure of the molecule or ion. Determine the arrangement of bond pairs and lone pairs. Assign the proper AX m E n designation.
VSEPR theory - Wikipedia
Valence shell electron pair repulsion (VSEPR) theory (/ ˈ v ɛ s p ər, v ə ˈ s ɛ p ər / VESP-ər, [1]: 410 və-SEP-ər [2]) is a model used in chemistry to predict the geometry of individual molecules from the number of electron pairs surrounding their central atoms. [3]
VSEPR Theory & Chart - ChemTalk
This VSEPR chart shows you all of the common VSEPR geometries, organized by the steric number and how many lone electron pairs they have. The steric number is how many atoms are bonded to a central atom of a molecule plus the number of …
VALENCE SHELL ELECTRON PAIR REPULSION (VSEPR) theory can be used to predict molecular geometry with high accuracy. The theory is based on Lewis structure and the principles that. valence electron pairs each other. the geometry around the central atom will be such as to minimize the electron repulsion. number (SN) is used to predict geometries.
VSEPR Theory - Chemistry Steps
To determine the geometry, we count the sum of the number of atoms and lone pairs around the central atom. This number is called the electron groups (EG) or steric number (SN) and it defines the geometry of the molecule. For example, let’s determine the steric number of Be in BeCl 2.

Once you know PCl 5 has five electron pairs, you can identify it on a VSEPR chart as a molecule with a trigonal bipyramidal molecular geometry. Its bond angles are 90 ° and 120 °, where the equatorial-equatorial bonds are 120 ° apart from one another, and all other angles are 90 °.
