the electron - pair geometry for the ammonia molecule is____ while the molecular geometry is____.
trigonal pyramidal
tetrahedral, trigonal pyramidal
bent, tetrahedral
linear, bent
trigonal planar, tetrahedral

Explanation:

The wedge - and - dash notation shows the 3D arrangement of atoms relative to the plane of the page. In ammonia ($NH_3$), the central nitrogen has 4 electron - pairs (3 bonding pairs and 1 lone pair), so the electron - pair geometry is tetrahedral. The molecular geometry, which ignores the lone pair in the shape description, is trigonal pyramidal.

Answer:

First question: plane of the page
Second question: tetrahedral, trigonal pyramidal
