Lewis Beverage cup structure in the case of ammonia is depicted by the outer electrons surrounding the nitrogen atom.
The Lewis point arrangement in the case of ammonia exhibits that the N atom joins one pair of electrons with each of the three H atoms, resulting in a total of 3 connected pairs of electrons.
The NH3 molecule takes a trigonal pyramidal form attributed to the distribution of the valence electrons according to its Lewis Beverage cup structure.
In the dot symbol representation of ammonia, the nitrogen atom is enclosed by three points, each representing a pair of united electrons with a hydrogen atom.
