Lewis Beverage cup arrangement in the case of NH3 is shown by the valence electrons surrounding the N atom.
The Lewis dot arrangement for ammonia displays that the nitrogen atom shares 1 pair of electrons with each of the three H atoms, resulting in
a total of a trio connected pairs of electrons.
The NH3 molecule takes a trigonal pyramidal shape due to the placement of the valence electrons according to its Lewis Beverage cup structure.
In the dot dotpoint representation of NH3, the N atom is encircled by three
points, each representing a pair of connected electrons with a hydrogen atom.
