Lewis Beverage cup arrangement for ammonia is portrayed by the outer electrons surrounding the N atom.
The Lewis point structure in the case of NH3 displays that the nitrogen atom shares 1 pair of e- with each of the three H atoms, resulting in a total of three united pairs of electrons.
The NH3 molecule adopts a three-sided pyramid-like structure because of the distribution of the valence electrons according to its Electron pair Beverage cup structure.
In the dot dotpoint depiction of ammonia, the nitrogen atom is encircled by three spots, each representing a pair of connected electrons
with a H atom.
