Electron pair dot arrangement in the case of ammonia is shown by the valence electrons surrounding the nitrogen atom.
The dot dot arrangement in the case of NH3 reveals that the N atom connects one pair of e- with
each of the three H atoms, resulting in a complete of 3 connected pairs of electrons.
The NH3 molecule takes a three-sided pyramid-like structure due to the placement of the outer electrons according to its Electron pair Beverage cup structure.
In the Lewis dotpoint representation of ammonia, the nitrogen atom is enveloped by three dots, each representing a pair of united electrons with a hydrogen atom.
