For the ammonia molecule write down the number of election pairs surrounding the central atom, number of atoms surrounding central atom and name used to describe the molecular
geometry.
The ammonia molecule consists of one nitrogen atom (N) as the central atom and three hydrogen atoms (H) surrounding it. Therefore, there are three electron pairs surrounding the central nitrogen atom. The molecular geometry of ammonia is described as trigonal pyramidal.
For the ammonia molecule (NH3):
