Lewis Beverage cup arrangement in the case of ammonia is a representation of the valence electrons surrounding the N atom. The Lewis dot arrangement for NH3 displays that the N 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 trigonal pyramidal structure due to the placement of the outer electrons according to its Electron pair Beverage cup arrangement. In the Lewis dotpoint depiction of ammonia, the nitrogen atom is surrounded by three points, each representing a pair of united electrons with a hydrogen atom.
