Electron pair Beverage cup arrangement in the case of NH3 is a representation of the outer electrons surrounding the N atom.
The Lewis point arrangement for NH3 reveals that the nitrogen 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 distribution of the valence electrons according to its Lewis Beverage cup structure.
In the dot dotpoint representation of NH3, the N atom is enclosed by three points, each representing a pair of connected electrons with a hydrogen atom.
