Quizplus · Accepted Answer

Ammonia (NH3) has four electron groups around the central nitrogen atom (three bonding pairs and one lone pair), making its electron group geometry tetrahedral. However, the molecular geometry considers the positions of the atoms only, resulting in a trigonal pyramidal shape due to the presence of the lone pair.
