Lewis Beverage cup arrangement in the case of ammonia is a representation of the valence electrons surrounding the nitrogen atom.
The dot dot structure for NH3 exhibits that the N atom shares a solitary pair of e- with each of the three hydrogen
atoms, resulting in a overall of three connected pairs of electrons.
The ammonia
molecule takes a three-sided pyramid-like shape due to the arrangement of the outer electrons according to its Electron pair Beverage cup structure.
In the dot dotpoint representation of ammonia, the N atom is surrounded by three spots, each representing a pair of connected electrons with a hydrogen atom.
