Formula
Steric Number = bonding pairs + lone pairs | Determines electron geometry → molecular geometry
Frequently Asked Questions
What is VSEPR theory?
VSEPR (Valence Shell Electron Pair Repulsion) theory predicts molecular shapes by assuming electron pairs around a central atom arrange themselves to minimize repulsion. Count bonding and lone pairs on the central atom, then use the steric number to determine geometry.
What is the difference between electron geometry and molecular geometry?
Electron geometry considers ALL electron pairs (bonding + lone) around the central atom. Molecular geometry only considers the arrangement of atoms (bonding pairs). For example, water has tetrahedral electron geometry but bent molecular geometry.
