Lewis Beverage cup arrangement for ammonia is portrayed by the outer electrons surrounding the N atom.
The Lewis dot structure for NH3 displays that the N atom connects one pair of e- with each of the three H atoms, resulting in a overall of 3 connected pairs of electrons.
The NH3 molecule takes a trigonal pyramidal shape because of the distribution of the valence electrons according to its Lewis Beverage cup structure.
In the dot dotpoint depiction of ammonia, the N atom is encircled by three spots, each representing a pair of united electrons with a H atom.
