Tetrahedral bond angle - Study guides, Class notes & Summaries

bond angle the angle (in degrees) defined by lines joining the centers of two atoms to a third atom to which they are chemically bonded valence-shell electron-pair repulsion theory (VSEPR) a model predicting the arrangement of valence electron pairs around a central atom that minimizes their mutual repulsion to produce the lowest energy orientations electron-group geometry the three-dimensional arrangement of bonding pairs and lone pairs of electrons about a central atom ...
