Lewis Beverage cup arrangement for NH3 is portrayed by the valence electrons surrounding
the nitrogen atom.
The Lewis point arrangement for ammonia reveals that the nitrogen atom shares a solitary 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 three-sided pyramid-like form attributed to the arrangement of the valence electrons according to its Lewis Beverage cup arrangement.
In the dot dotpoint representation of NH3, the N atom is enveloped by three dots, each representing a pair of shared electrons with a H atom.
