Lewis Beverage cup structure in the case of NH3 is illustrated by the outer electrons surrounding the nitrogen atom. The dot dot arrangement in the case of ammonia reveals that the N atom shares a solitary pair of e- with each of the three H atoms, resulting in a complete of three connected pairs of electrons. The ammonia molecule adopts a trigonal pyramidal structure because of the arrangement of the valence electrons according to its Lewis Beverage cup structure. In the Lewis dotpoint representation of ammonia, the nitrogen atom is surrounded by three points, each representing a pair of connected electrons with a hydrogen atom.
