Electron pair dot arrangement in the case of ammonia is portrayed by the outer electrons surrounding the N atom.
The dot point arrangement for NH3 reveals that the nitrogen atom unites 1 pair of electrons with each of the three H atoms, resulting in a overall of three shared pairs of electrons.
The NH3 molecule adopts a three-sided pyramid-like shape
due to the distribution of the outer electrons according to its Lewis Beverage cup structure.
In the Lewis dotpoint depiction of ammonia, the N atom is enclosed by three spots, each representing a pair of united electrons with a H atom.
