Ammonia Molecule Structure - NH₃ Geometry and Bonding #9092 (License: Personal Use)

This diagram illustrates ammonia (NH₃), a polar molecule with trigonal pyramidal geometry due to sp³ hybridization and one lone electron pair on the central nitrogen atom. The bond angle is approximately 107°, slightly less than the ideal tetrahedral angle of 109.5° because of greater repulsion from the lone pair. Wedge-dash notation indicates spatial orientation: solid wedge = bond coming forward, dashed lines = bond receding, plain line = in-plane bond.

Used in educational chemistry content (textbooks, MOOCs, lab guides) to teach VSEPR theory, molecular geometry, hybridization, and polarity; matches user intent for visual learning or quick reference during study or instruction.
