Electron pair dot structure in the case of ammonia is portrayed
by the outer electrons surrounding the nitrogen atom.
The dot point structure for ammonia reveals that the N atom shares one pair of e- with each of the three hydrogen atoms, resulting in a total of 3 united pairs of electrons.
The NH3 molecule takes a trigonal pyramidal form attributed to the placement of the outer electrons according to its Electron pair dot structure.
In the dot dotpoint representation of NH3, the nitrogen atom is surrounded by three dots, each representing a pair of joined electrons with a hydrogen atom.
