Lewis Beverage cup arrangement for ammonia is portrayed by the valence electrons surrounding the N atom. The Lewis dot structure in the case of NH3 reveals that the N atom unites a solitary pair of electrons with each of the three H atoms, resulting in a complete of three joined pairs of electrons. The ammonia molecule takes a three-sided pyramid-like structure due to the distribution of the outer electrons according to its Lewis dot arrangement. In the Lewis symbol depiction of NH3, the nitrogen atom is enveloped by three spots, each representing a pair of shared electrons with a hydrogen atom.
