Lewis Beverage cup arrangement in the case of NH3 is a representation of the outer electrons surrounding the nitrogen atom.
The Lewis point structure for NH3 reveals that the nitrogen atom connects a solitary
pair of electrons with each of the three hydrogen atoms, resulting in a complete of three joined pairs of electrons.
The ammonia molecule adopts a trigonal pyramidal shape attributed to the distribution of the valence electrons according to its Electron pair dot arrangement.
In the Lewis symbol representation of NH3, the N atom is enclosed by three dots, each representing a pair of connected electrons with a H atom.
