Lewis Beverage cup structure for NH3 is portrayed by the valence electrons surrounding the nitrogen atom. The dot dot arrangement in the case of ammonia reveals that the nitrogen atom unites 1 pair of e- with each of the three H atoms, resulting in a complete of three united pairs of electrons. The ammonia molecule takes a trigonal pyramidal shape attributed to the arrangement of the outer electrons according to its Lewis Beverage cup structure. In the Lewis symbol depiction of ammonia, the nitrogen atom is enclosed by three spots, each representing a pair of shared electrons with a hydrogen atom.
