in the lewis dot structure for nh3, the central atom of the molecule has three atoms bonded to it and one lone pair of electrons. the shape of an nh3 molecule is bent. tetrahedral. trigonal planar. trigonal pyramidal.

Answer

Answer:

D. trigonal pyramidal

Explanation:

Step1: Recall VSEPR theory

Valence - shell electron - pair repulsion (VSEPR) theory is used to predict molecular geometry.

Step2: Determine electron - pair geometry

N in NH₃ has 3 bonding pairs and 1 lone pair. Total electron - pairs around N is 4. Electron - pair geometry is tetrahedral.

Step3: Determine molecular geometry

Lone - pair repels bonding pairs more strongly. With 1 lone pair and 3 bonding pairs, the molecular geometry of NH₃ is trigonal pyramidal.
