Lewis dot arrangement for NH3 is portrayed by the outer electrons surrounding the nitrogen atom. The Lewis dot structure in the case of ammonia reveals that the N atom unites 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 structure due to the distribution of the outer electrons according to its Lewis Beverage cup structure. In the Lewis symbol representation of NH3, the N atom is surrounded by three spots, each representing a pair of united electrons with a hydrogen atom.
