Electron-Pair Geometry
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Electron-pair geometry describes the arrangement of every electron domain, bonding and lone pair alike, around a central atom.
Show
Ammonia's central nitrogen has four electron domains, three bonds and one lone pair, giving a tetrahedral electron-pair geometry.
Watch for
Electron-pair geometry counts every domain including lone pairs — Chem 1040 names the narrower term counting only bonded atoms.
